Dev Manifest error while saving changes in the Extensions Dashboard


Anyone else having errors while trying to save changes like whitelisting URLs on the extensions dashboard?

“Error Your request could not be completed at this time. Please double check the format of your request and try again…”
Same happens if you try to whitelist a testing account.

Inspecting the error in the console, it seems to be an issue on Twitch’s side “DevSaveExtensionVersionManifest” is the name of the operation that seems to be failing with;
“[GraphQL] [DevSaveExtensionVersionManifest] One or more GraphQL errors were detected…”

Edit: On closer inspection, the actual error message is:
“TargetHeight is required, and cannot be 0”

Relog on the dashboard and retry your request
