Quick question about analytics API 422 on custom metric update

Quick question about the analytics API rejecting updates to custom metric definitions. The CLI push fails with 422 Unprocessable Entity, citing a validation error on the expression field despite local JSON schema validation passing.

Environment details:

  • Genesys Cloud CLI v2.1.0
  • AU-1 BYOC
  • Terraform Genesys provider v1.15.2
  • JSON payload matches API spec exactly

Any known issues with expression parsing in this region?
