cannot process API call for unknown reason, or incorrect configuration ?

[FabricBeginner]

Hello,

I am totally new here...
I need to create 35 api calls and processed each api anser into table, and getting an error

Here is my solution
I created lookup which return one column with 35 rows (that is OK), and send it to FOR EACH activity, inside FOR EACH is dataflow gen 2 which should process the data, but getting an error

Error code

20302

Failure type User configuration issue

Details

Dataflow refresh job failed with status: Failed. Failure reason: { requestId: xxxxxxxx, errorCode: EntityUserFailure, message: Something went wrong, please try again later. If the error persists, please contact support. }

Lookup settings

For Each settings

DataFlow settings

DataFlow settings

totally weird is that when I take value various value from Lookup (URL column) and put it into parameter in dataflow gen 2 and run it isolated then works fine
