Can't convert issue to discussion — ConvertToDiscussionDialogQuery returns a server error

[aidenlx]

Converting an issue to a discussion fails with a generic server-side error.

The failure happens on the ConvertToDiscussionDialogQuery GraphQL request — i.e. when the "Convert to discussion" dialog loads, before a target category can even be selected. The conversion never gets far enough to be attempted, and the error carries no actionable detail.

Details for log lookup:

• Request ID: A5A0:1BB6D7:CD6413:104D717:6A64E92F
• Timestamp: 2026-07-25T16:49:56Z
• Affected issue: [FR] Support multi-source citation insertion aidenlx/zotlit#496
• Repository: aidenlx/zotlit (public)

Ruled out on my side: Discussions is enabled on the repo with categories configured, and I own the repo, so permissions and feature setup shouldn't be factors.

No workaround available. There's no public GraphQL mutation for converting an issue to a discussion — createDiscussion doesn't carry the issue over, and no convertIssueToDiscussion exists in the schema. The web UI is the only path, so when it errors there's no alternative.

Happy to reproduce and collect additional request IDs if that would help narrow it down.
