What Operating System are you using (both controller, and any agents involved in the problem)?

Ubuntu 20.04.6 LTS

Reproduction steps

1. Install plugin version 2.49.
2. Create a Jenkins job with an "Execute shell" build-step:

cat <<EOF >  code-changes.patch
Line 1 of the file
Line 2 of the file
Line 3 of the file
EOF

3. Add Post-build Actions -> Slack Notifications -> Notify Success -> Include Custom Message:

4. Also switch on Upload build artifacts and type in there code-changes.patch: 5. Run the job. Check in the slack channel the message and file are posted. 5. Update plugin to version 761.v2a_8770f0d169. 6. Run the job.

Expected Results

The custom message and message with file code-changes.patch is posted to the channel.

Actual Results

The custom message is posted to the channel, but message with file code-changes.patch is not posted.

No errors in the log, no file mentions as well. Here OnSuccessNotification snippet:

Posting: to localization on company: {"attachments":[{"fallback":"PE Mac Code Localizable Strings Changes Canary - #47127 Success after 2.9 sec \nHello, localization robot speaking :robot_face:\nProgrammer(s) have just changed some localizable strings in 'PEM Localization'.\n@translators please find the list of changes in the attached file below ⬇️","color":"good","fields":[{"short":false,"value":"PE Mac Code Localizable Strings Changes Canary - #47127 Success after 2.9 sec \nHello, localization robot speaking :robot_face:\nProgrammer(s) have just changed some localizable strings in 'PEM Localization'.\n@translators please find the list of changes in the attached file below ⬇️"}],"mrkdwn_in":["pretext","text","fields"]}],"link_names":"1","unfurl_links":"true","unfurl_media":"true","channel":"localization","as_user":"true"}

Anything else?

Also we checked upload manually and it did work:

curl -F file=@code-changes.patch \
     -F "initial_comment=🛠 Changes attached below" \
     -F "channels=#localization" \
     -H "Authorization: Bearer $SLACK_TOKEN" \

Yes, cloud-rd2-ci is the right app (see my screenshot of a message in the channel above). Also, as I mentioned in the issue description, cloud-rd2-ci posts custom message from the job configuration, but does not post a file from build artifacts.

We have almost all these scopes #1074 (comment)
Any additional configuration screenshots could be helpful? Slack bot or Jenkins job.
