How to fix this: Azure Function Deployment Error: App Service Plan Create Operation is Throttled (Code 429)

Question

I faced this issue when I was deploying a function app.

Has anyone encountered this error before, and if so, what steps can I take to resolve the throttling issue? Is this related to a limit on App Service Plan creation, or is there something else I should look into?

I would appreciate any suggestions on how to address this and prevent it in the future.

Answer 1

Thanks for posting your question in the Microsoft Q&A forum.

Review your subscription's limits for App Service Plans. You may be approaching or have reached the maximum number of plans allowed.

If you're using automated deployment scripts, implement exponential backoff retry logic to handle throttling errors gracefully

If you're deploying multiple function apps, try to space out the deployments rather than creating many plans simultaneously
