Research direction
Reproduce the three failing calls in the playtest environment, then start by tracing the GenericPluginClient.SubmitCustomPost and GenericPluginClient.Submit errors. Confirm whether the USER, APP, and fallback submission paths share the same failure; the work is done when custom and plain post creation succeed in playtest.

Description
Environment:
- Subreddit: r/mydevvitbottest2
- Devvit CLI: @devvit/cli/0.12.23-next-2026-05-05-17-20-47-e5daaf644.0
- @devvit/web: 0.12.23-next-2026-05-05-17-20-47-e5daaf644.0
- Node: v20.19.0
Problem:
Both reddit.submitCustomPost() and fallback reddit.submitPost() fail in playtest with:
Error: undefined undefined: undefined
This happens for:
submitCustomPost({ runAs: 'USER', entry: 'default', userGeneratedContent, textFallback })submitCustomPost({ runAs: 'APP', entry: 'default', textFallback })submitPost({ runAs: 'APP', text })
All post creation calls fail with the same gRPC error:
GenericPluginClient.SubmitCustomPostGenericPluginClient.Submit
What I already tried
- Added
permissions.reddit.asUser: ["SUBMIT_POST"]todevvit.json - Uploaded a fresh version and explicitly installed
queuecurb@0.0.2tor/mydevvitbottest2 - Confirmed the local playtest CLI is already on
0.12.23-next - Rebuilt and restarted playtest cleanly
- Verified the same failure happens for both USER and APP runs, and also for plain
submitPost()
