Deploy on Railway from the fork dev branch, and hit an error

To Reproduce
Steps to reproduce the behavior:
Follow the instruction on this link:
https://github.com/ftx-class-action/RSS-to-Telegram-Bot/blob/dev/docs/deployment-guide.md

got the token (##9:A##)from @Botfather
got the user id (mine -> 1##2) from @userinfobot
got the api token (access_token: 67***12) from the url
Fork the repo
Deploy on Railway (dev branch)
when done, go the following error:
telethon.errors.rpcerrorlist.NeedMemberInvalidError: The provided member is invalid or does not exist (for example a thumb size) (caused by SetBotCommandsRequest)

I got the user Id from @userinfobot, and confirm my account info is correct, not sure why complained about member is invalid. Should I turn off multiuser mode?

The fork was off the latest dev branch.

Expected behavior
no error, deployment successful

Describe the bug
多数 Telegram 客户端会把 webp 图片当作贴纸看待，而贴纸是没有文本内容的（实际用API可提取文本内容）

To Reproduce
Steps to reproduce the behavior:

1. 找一个能提供（内容中包含）webp图片的rss源
2. 机器人上点订阅
3. 然后看推送就会发现文本内容消失了

Expected behavior
将webp图片转换成其他任意格式

Important log
这应该属于Telegram客户端渲染的问题，服务端应该不会收到任意错误信息，因此也无法提供有意义的日志

带图片反代的地址在rsstt中无法正确解析，导致展示为invalid image
例如：

中的图片地址被解析为：

其中/plain/https:/ 应为 /plain/https://

即http://反代服务器/imgproxy/plain/https://gd-hbimg.huaban.com/851fe532c64071d617b54f0f5fe1a52cc7dfdcad1cb39b-BvTi90

/set_default :
Interval=1h
Notifications=normal
Send mode=force telegraph
Length limit =unlimited
Media =enable
Post title =enable
Author=enable
Style=rsstt

When I tap on instant view there is a "more" and a "source" link

Whichever I select I am first redirected to the original site and only the second time the telegraph.ph generated page is opening

Is there a way to really "force" to first display the telegraph generated page?

Describe the bug
Once used bulk subscription upload I'm getteing "Reply with file..." being presented on mobile and desktop client. Did that with 2 instances: Heroku & VM + docker - same effect. That lead to situation when once going to chat I'm being moved to bottom of chat instead of head of "Unread".

To Reproduce
Steps to reproduce the behavior:

1. launch dockerized instance
2. use /import
3. upload *.opml
4. See error: now and then, you will see on all devices message "Reply with file..." on client which initiated action and other (desktop/mobile)

Expected behavior
Once replied with file, message to reply don't appear any more.

<media:content> in Media RSS not extracted: https://t.me/RSStT_Group/4434

Note: <media:group> is ignored, better to fix the upstream issue first. kurtmckee/feedparser#195

Please could you advice on how can I modify the default template to achieve this kind of design:

Title
full link (https://.....)

For examle, I like to use this style:

I tried several parameters and this is the closest thing that I was able to get:

Please advice, I installed the script and got my private bot working, but I noticed that if I use the /set parameter inside the Telegram app in order to modify the feed, then many features are missing compared to the public bot.

你好我参考了readme在群晖的docker上部署了但是从telegram的机器人输入command没有响应，部署 BoKKeR 的原版功能正常，以下是运行日志，想了解一下哪里操作上出现问题，非常感谢！

hello
can you add some sort of filtering?
example i want it post when content include certain word
or forward post contain certain word to another chat.
or after posting in telegram delete post that not contain defined word

thanks

I'd like to see support for the self-hosted Telegram API server available over here: https://github.com/tdlib/telegram-bot-api. That offers some quite neat advantages instead of api.telegram.org, especially when having multiple bots hosted on same infrastructure.

Ability to exclude/include posts by original author (like if the post is a retweet) author, hashtags, text, title, etc.

Also consider adopting https://github.com/Delgan/loguru

The current flood control workaround is lock-and-retry-based. In most cases, it works fine. However, some feed updates a lot of posts in a bunch every update period. With the current workaround, most posts are unable to be sent due to timeout or too many retries.

This feature aims to initiatively limit the sending speed of each chat. It should help work around this problem a lot.

Hey, I'm using the bot to read Twitter via nitter RSS. And sometimes nitter is rate limited and links to tweets don't work.
Is it possible to get a custom URL replacement in output, for example, change nitter.net for twitter.com in all URLs, including the source link.
Thanks.

Hello,

This feed, which works in the browser, will not work in the script.

Failed to subscribe
https://www.rt.com/rss/ (ERROR: HTTP status code error (403 Forbidden))

When I curl the feed URL, I see that I'm getting a security screen of code for DDoS-Guard that has a five-second delay before being forwarded to the RSS Feed data. Once a cookie is set, the next visit is not bothered by DDoS-Guard.

What do you recommend in this situation where a delay, cookie, and redirect need to be followed to obtain a feed?

Describe the bug
I've monitoring this subreddit with your bot, and some posts are missing links ([link] and [comments])

To Reproduce
Steps to reproduce the behavior:

1. Subscribe to https://www.reddit.com/r/FreeGameFindings/.rss in bot
2. Wait for posts
3. Most posts will be missing [link] and [comments] links

Expected behavior
Have the [link] and [comments] links, as expected

Describe the bug
When using RSS with emojis in title, it does not correctly post the same emoji as the title in the Telegram message. It looks like:

๐ŸŒŠ๐Ÿ„ Amoogust Update 2022 - The Nightly Build Switch Update (Revision B) | Changes

See:

To Reproduce
Steps to reproduce the behavior:

1. Let the feed post it as Telegram message
2. Use /test https://news.mailcow.email/index.xml

Expected behavior
See emoji.

Important log
n/a

I have several issues with preset styles, the most important ones are:

• Underlining the title.
• displaying the word "Source" as hyperlink.

These two easily ruin the appearance of Persian/Arabic feed's posts.

Also, I want to use an emoji before the title and content but it looks like it's not possible.

I think adding the ability to customize the style and format of each feed's posts using Markdown (or HTML) and placeholders would permeantly solve the style issues.

#118 #130

Telegram bots are public by default.
Everyone that knows the bot name can contact the bot and start a chat with it.
It would make sense for those self hosting the bot for personal use to have a feature that makes the bot respond only to it's "creator"

Btw
Thanks for the great project and keep up

how unsub from feed?
i put bellow command
/unsub @username
in private chat that i am in with bot only
return this
This command can only be used in a private chat.

how solve this?

Describe the bug
Posts are not in the correct order as in the source feed.

Hello I want the RSS feed to update every 1min, but that's not possible because of this error.
I'm hosting using Docker, is there any way I can circumvent this?

一个建议，加了下划线比较影响视觉观感。

Describe the bug
Since december 16 posts from reddit rss have wrong links, all /u/, [link] and [comments] links are wrong, they all point to https://www.reddit.com/r/<subreddit>/.rss

To Reproduce
Steps to reproduce the behavior:

1. Subscribe to https://www.reddit.com/r/FreeGameFindings/.rss in bot
2. Wait for posts.
3. Links will be wrong.

Expected behavior
Have correct links.

Important log
You may execute docker logs [container name] to get log.
Choose that is important and paste it here.

Just a quick feedback: IMHO I think it would be neat to disable the link preview when /help is being used.

Reasons:

1. It makes the output so large. On smaller windows (e.g. having client on portion of the screen) it makes it a bit difficult to read at once or needs to scroll.
2. Above is especially annoying, when bot is being set-up the first time and often scrolling for commands is required.
3. During night time and using dark mode, the link preview screenshot with the bright white background makes you almost blind.

Just as an example:

你好，使用最新版的rsshub生成的微博源无法正确展示视频，显示为invalid video，在境内自建freshrss阅读器中展示正常，希望修复该问题，非常感谢！

通过 Docker 安装。

This will be a very useful feature as a lot of the time with RSS feeds, there's a lot of noise, with a lot of news that isn't relevant.
So if we could blacklist certain words/strings from appearing in the feed that would be an extremely useful feature.
