### Confirm

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

Start by locating the type definition for Microsoft.Web/connections at API version 2016-06-01 and inspect how the resource's kind property is represented. Confirm the definition supports the reported V2 value and validate the generated Bicep type output using the repository's available checks; done means the repro is accepted without a missing-property error.
