We only provide the pipelines as starter pipelines. It's up to you to modify them as you see fit. As long as the publisher finds that file to publish it then you should be fine. What happens prior to that can be altered as you see fit. Just make sure the format of your directory is intact as the publisher expects a certain structure which is what the extractor is providing.

I have tried open api merge cli to merge two open API specification files and it seems merging is working as expected. However, pipeline is throwing the below error. it would be great if you could provide some suggestions.

It worked when I changed the API_MANAGEMENT_SERVICE_OUTPUT_FOLDER_PATH parameter from $(Build.SourcesDirectory)/${{ parameters.API_MANAGEMENT_SERVICE_OUTPUT_FOLDER_PATH }} to "BO APIOps Test/artifacts"

Since I'm a beginner in yaml pipelines, I couldn't find any other issues with the yaml.

The publisher needs to know where your artifacts are located. It gets that value from the configuration value API_MANAGEMENT_SERVICE_OUTPUT_FOLDER_PATH. By default, our starter pipelines set it to $(Build.SourcesDirectory)/artifacts here, here, and here.

You can change this as per your comment above, or by changing this to BO ApiOps Test/artifacts.

@guythetechie When I merge and deploy openapi files using the above pipeline the following error is thrown.

The strange thing is that the same merged file from the above pipeline is successfully deployed through the starter pipeline. any thoughts?
