Delay Agent, undefined method `payload' for nil:NilClass about huginn HOT 7 OPEN

OK, so I did a little bit more testing. The non-existent events weren't the problem after all.

It actually looks like this error always occurs when the number of events in memory is lower than max_emitted_events (but not when the memory is empty).

What's the URL to the RSS feed?

from huginn.

If I can guess, the payload was empty. So, maybe the feed was unreachable? Or was malformed?
Now I deleted all jobs with errors. I can't reproduce, feeds are running smoothly again.
I have an array of feeds getting parsed by the agent, I can't say which one had errors.
I will say in the future, if will happens again. Maybe I can close this issue for now.

I write to reopen this issue, because I ran again in the same error.
This error is about Delay Agent (I'm limiting the flow to 1 rss item per hour)

I can't get the "event in", should have been a RSS Agent output. Like this

This is an example of working payload

I just updated my installation on Heroku from a95c5cc to he newest commit 2d5fcaf and started seeing the same log messages regarding the Delay Agent.

This error seems to occur when the agent's memory contains IDs of events that don't exist any more. After manually deleting the memory of the affected agent it started working normally again.

Previously such IDs were simply ignored by the Delay Agent and didn't cause any issues. It would be great if that behaviour could be restored because currently any incoming events may be emitted 5 times before the job goes to "failed" status.

now I also struggle in such problem. Is there anyone who can fix this bug of Delay agent?

from huginn.

Same here. Is there any way to work around?
