Expanding extensions for todo tasks is throwing 500 error 'expected EntitySet or Singleton'

Question

GET /users/{Id|userPrincipalName}/todo/lists/{todoTaskListId}/tasks/{Id}?$expand=extensions($filter=id eq '{extensionId}')

is throwing 500 Internal Server Error.

"error": { "code": "InternalServerError", "message": "Expected EntitySet or Singleton"}

I am unable to find any documentation on any recent breaking change which is causing this and if any format change is needed in query. Please provide necessary guidance.

This started to happen just recently and there is no documentation online, why such error is getting thrown and how to fix it. I'm using NodeJS for calling this API btw

Answer 1

This has been fixed. I have tested and it should be working fine now.
