Severity: error

This diagnostic is issued when TCGC cannot resolve an operation as an HTTP or HTTPS operation.

Impact

Section titled “Impact”
  • Area: Service method generation. Blocks creating a TCGC service operation for a non-HTTP/non-HTTPS protocol operation.
  • Not affected: The TypeSpec operation can still exist outside TCGC HTTP client generation.

Diagnostic Message

TCGC reports:

Currently we only support HTTP and HTTPS protocols

✅ How to Fix

Section titled “✅ How to Fix”

Add appropriate HTTP route and verb decorators to the operation, or remove it from the TCGC-generated client surface.
