discussion is not an Announcement

Error message

discussion is not an Announcement

What it means

discussionFromEnvironment builds the discussion object purely from workflow-provided env vars, but only permits use when DISCUSSION_CATEGORY is exactly 'Announcements'. The throw enforces that the injected discussion actually lives in the Announcements category, since the script only posts receipts into announcements.

Solutions

1. Set DISCUSSION_CATEGORY=Announcements in the workflow env
2. Move the target discussion into the Announcements category
3. Use the GitHub-lookup path instead by passing DISCUSSION_NUMBER for a discussion already in Announcements
4. Trim/case-normalize the comparison if upstream providers vary the value

Example fix

// before
if (env.DISCUSSION_CATEGORY !== 'Announcements') throw new Error('discussion is not an Announcement');
// after
if (env.DISCUSSION_CATEGORY?.trim() !== 'Announcements') throw new Error(`discussion is not an Announcement (got: ${env.DISCUSSION_CATEGORY})`);

// guard in the workflow before the script runs
if (process.env.DISCUSSION_CATEGORY !== 'Announcements') {
  throw new Error(`DISCUSSION_CATEGORY must be 'Announcements', got: ${process.env.DISCUSSION_CATEGORY}`);
}

function isAnnouncementEnv(env) {
  return env.DISCUSSION_CATEGORY === 'Announcements'
    && typeof env.DISCUSSION_ID === 'string' && env.DISCUSSION_ID.length > 0;
}

try {
  const discussion = discussionFromEnvironment();
} catch (err) {
  if (err.message === 'discussion is not an Announcement') {
    console.error(`DISCUSSION_CATEGORY=${process.env.DISCUSSION_CATEGORY}; expected 'Announcements'`);
  }
  throw err;
}

When it happens

Trigger: Env-provided path selected (DISCUSSION_ID etc. present) but DISCUSSION_CATEGORY env var holds any other value — e.g. 'General', 'Ideas', unset-and-defaulted, or differently cased like 'announcements'.

Common situations: Workflow step wired with DISCUSSION_ID/DISCUSSION_TITLE but forgot to pass DISCUSSION_CATEGORY; CI passes the category of an existing discussion that lives in a non-announcement category; case sensitivity mismatch.
