Hi everyone,
I'm building a flow which creates a task in Planner using a PlanId and BucketId retrieved from a sharepoint list.
I defined and set a two strings variables with the values of PlanId and BucketId and I passed them to the create planner task, as showed below.

When I run the flow I encounter this error:
" Schema validation has failed. Validation for field 'PlanId', on entity 'Task' has failed: The specified identifier is invalid. "
So I've tried to insert in the task input the actual values of the Plan e Bucket Ids, and the flow ran successfully.

I've checked also the raw input and they are the same in both cases.
Someone could help me with this issue?
Thank you,
Valerio
