DevOps deploy fails to delete web app. Error "exclusive lock to create, update or delete"

Question

Hey all,

I have a release-pipeline where I have a step that deletes a deployment slot. This works fine when only deploying to one Web App in the same App Service Plan. But, if I deploy to multiple Web App`s sharing the same App Service Plan, the step fails and returning the below error.:

Error: Failed to delete App Service slot 'webapp-deployment'. Error: 429 - Cannot acquire exclusive lock to create, update or delete this site. Retry the request later. (CODE: 429)

I`m using “-force” in my script but have no effect on this matter.

Answer 1

I have found the solution, and that is to run the PS script with "-AsJob".
