### Confirm

- [X] I have read the troubleshooting guide and looked for duplicates.

Start with the Bicep repro for Microsoft.DataFactory/factories/pipelines@2018-06-01 and inspect the type definition for AzureDataExplorerSink. Confirm how the missing additionalProperties field is represented; done means the repro no longer reports BCP037 for that property.
