Modmail Conversations throw a TypeError when issuing a reply about praw HOT 13 CLOSED

Could you include the the full exception?

from praw.

Oh whoops, realized I missed the last line. Went ahead and ran this on my non personal account so I don't have to redact the path, as well:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/dppmods/testing/.venv/lib/python3.9/site-packages/praw/util/deprecate_args.py", line 43, in wrapped
    return func(**dict(zip(_old_args, args)), **kwargs)
  File "/home/dppmods/testing/.venv/lib/python3.9/site-packages/praw/models/reddit/modmail.py", line 265, in reply
    message_id = response["conversation"]["objIds"][-1]["id"]
TypeError: 'ModmailConversation' object is not subscriptable

Just to confirm this used to work? This is likely a change with how Reddit is returning data. By looking at the exception it seems like the serializer is objectifying things too soon.

from praw.

Yep. This code's been working reliably 30+ times a day since (at least) March.

from praw.

Then yeah this is Reddit making a breaking change. Again. I'll dig deeper into it and see if I can get it working.

from praw.

This only happens with internal messages? Can you find cases where it works as intended?

from praw.

External replies as well, per recent brief testing. I'll have a think about other possible test-cases and report back should I think of anything.

from praw.

So any reply is broken? Interesting. That makes this more severe. If replying is completely broken then this needs reported to Reddit.

from praw.

The replies go through just fine, to be clear; it looks like it's just sending different data than praw expects back.

Weighing in - all seeing this error. Have been using reply() to modmail for years+ and reddit broke it within the past few days. The reply is sent but an exception is generated

from praw.

derp

"all seeing this error" = also seeing this error

from praw.

@spitrespectable if you also archive your messages after reply by bot and this breaks that, in the interrum I've found that, since the reply does get sent, you can wrap it in a try/except to be able to still archive modmails

try: conversation.reply(<reply stuff here>)
except: pass
conversation.archive()

This should be fixed now. Releasing to PyPi now.
