Describe the bug

For an N:N relationship, the CLI allows to add the intersect table as a source. The generated service includes the usual methods. Attempting to create a new relation using the create() method fails. Reading with getAll() works.

Code Apps documentation doesn't mention any limitations or recommendations around N:N relationships (that I could find).

Steps to Reproduce

pac code add-data-source -a dataverse -t <intersect-table-logical-name>
Try to create a record using the generated service
See error

Expected behavior

New record created in intersect table.

Actual behavior

Request fails with error message.
