Expected behavior

The TypeError indicates we may need to do some extra checking of the loaded-in Slack adapter, and possibly switch behavior if the uploadV2 method is not present.

Software:

Additional context

Add any other context about the problem here.

It looks like it's getting the image itself without issue, but running into trouble with a mismatch between the (now legacy) Slack adapter for Hubot and the @slack/web-api version. Not entirely sure what it should try to fall back to.

Switching back to the old method might work, but I would advise to upgrade anyway, as files.upload is deprecated and will stop working on March 11, 2025. New app are not able to use it since May 8, 2024.

same issue I facing with, is it possible to fix the issue before files.upload retired, please

[stephenyeargin]

I'm a bit fuzzy on it, but I think anyone using the current hubot-slack adapter is going to lose access next month, irrespective of this package. 😞 Organizations will need to swap over to @hubot-friends/hubot-slack, which has a different set up process.

[stephenyeargin]

Finally got it back up and running. One thing to note is that files:write isn't mentioned in the default manifest for @hubot-friends/hubot-slack, so that may be an extra step. Added it as a note in the wiki.
