Azure pipeline not working for production

Question

I want to deploy 3 Service Bus Resources using the azure pipeline.

1. amit-dev - for dev environment.
2. amit-tst - for the test environment.
3. amit-prd - for PRD environment

test and dev don't need approval, but prd deployment needs approval.

my pipeline is able to deploy dev and test resource without any problem, It asks for approval when it comes to prd deployment, But then it stops with error message :

Creating deployment parameters.

Here is my pipeline code.

                    deploymentMode: 'Incremental'

I fail to understand why prd deployment is giving errors, whereas the same lines of code work for test and dev environments without any issues.

Answer 1

Job and deployments are different in nature. By default, job will download the repo but deployment will not. Just mentioned checkout: self in deployment and it fixed my issue.
