What version of Dapr?

1.10.3

Expected Behavior

Calling the Dapr metadata API returns as expected with no additional calls.

Actual Behavior

With every call to the Dapr metadata api, the pubsub programmatic subscriptions /dapr/subscribe endpoint is being called. This is fine if the app that is being called has a definition for /dapr/subscribe but if there is no function definition, you will receive errors in your app and phantom calls to your application.

Reference PR where this was introduced here: eeca309#diff-e56f9bb947923c6f8bb4c995bf4b9469a0ed117276223d16b177dcb04399a4bc

Steps to Reproduce the Problem

Deploy Dapr app without programmatic subscriptions, and thus no /dapr/subscribe endpoint and hit the metadata API. Notice the failed call to the /dapr/subscribe endpoint.

Huge thanks to @filintod for helping spot this!

Release Note

RELEASE NOTE: FIX Remove programmatic subscription call from metadata API
