Set Pipeline Return Code using Dynamic Content

Question

I have a pipeline that has one job: use a Web activity to get an Access Token to be used in other Web activities. Those other web activities in other pipelines so to simplify the design, I want to call the first pipeline from within the second (and many other) pipeline(s). So in the first pipeline, I have a task that sets the Pipeline return value, and for the Value, I put in the dynamic content just as I would if I was setting a Pipeline variable:&nbsp;@activity('Request an Access Token').output.access_token
Note that the dynamic content expression yields the proper value if it is used to set a pipeline varialbe, but when used to set a return code, the result is simple the literal expression of "@activity('Request an Access Token').output.access_token".
&nbsp;
Question, how do I set a pipeline return value using dynamic content?

Going to take a wild guess here.Have you changed the type of the pipeline return value to 'Expression' instead of 'string'?

I did a simple 2 pipeline workflow, the first calls the second and sets a variable based on the return value from the second. (the second pipeline just has a Get Metadata step and outputs that as its return value.

Inner pipeline - you've seen the Set Variable in the picture above.
