I am trying to retrieve the Metadata about table/views and their columns in SAP Fieldglass using Azure Data Factory.

The second WEB activity is failing with...

<Status>
  <TransactionID>z2502071518487075872499e</TransactionID>
  <ReturnCode>255</ReturnCode>
  <Message>Illegal group reference</Message>
</Status>

Headers Authorization: Bearer @{activity('TEST_API').output.access_token} X-ApplicationKey: XXXXXXXXXX for the Second Web Activity.
