[BUG]Extractor pipeline getting failed at Fetch Extractor step when trying to extract definition for single API after adding tokenization to change API name in different environment

Start with the attached run-extractor.yaml.txt and compare its Fetch Extractor step with run-publisher.yaml.txt and run-publisher-with-env.yaml.txt. Trace how the releaseFileName variable is set before the failing download in the reported PowerShell error. Done means the extractor completes and places the single API definition in a separate folder; publishing guidance for specific or new APIs should also be addressed.

Release version

APIOps toolkits for Azure APIM v6.0.1.1

Expected behavior

It should be extracted in a separate folder

Actual behavior

at Fetch Extractor step it is getting failed and not extracting the definition also need to know steps for publishing specific APIs or new APIs only, rather than all APIs in the Azure DevOps Repos.
