[Text Analytics] Transient Internal Server Error: "Invalid Task Type"

[joseharriaga]

The pipeline that runs the live tests for the .NET client library encounters this issue every now and then, where the server returns an "Internal Server Error" claiming that a certain task is an "Invalid Task Type" and that it is "not supported". The request is actually valid though, and retrying it usually yields a successful result. Below is an example of the response, which claims that "extractivesummarization is not supported". I've seen this error repro with other kinds of tasks too, such as healthcare. Additionally, while I'm not able to confirm the following, I believe that this only repros when using the analyze-text/jobs endpoint.
