Signals Notebook: Creating a material batch via the Signals API failed after adding an Internal Reference field to the record definition

Description: After adding a new Internal Reference field to the batches of a material library record definition when attempting to create a batch by sending the link value the batch creation fails with the error "The request parameters are in bad format. ERROR: insert or update on table [...]violates foreign key constraint".

Cause: This can happen if a link/url value is being used instead of the eid of the entity to reference.

Solution: Use the supported Internal Reference type field payload format in the request body:

• Individual value reference field:
          {
           "id": "xxxxxxxxxxxxxxxxxxxxxxxx",
           "value": {
                         "eid":"experiment:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
                        }
         }

• Multiple values reference field:

         {
          "id": "6a308665de15624ab114535d",
          "value": [
                         {
                             "eid": ""experiment:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
                         },
                         {
                             "eid": "experiment:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
                         }
                     ]
         }
