CHW-4841 PodspecInvalid

podspec failed validation; verify the name, version, and source fields

Default message: podspec failed validation; verify the name, version, and source fields
HTTP status: 422 (client)

Problem. pod trunk push was rejected with 422. Cause. The posted podspec failed validation — typically a missing name, version, or source field. The validator’s per-field message is surfaced via WithMessage so the CLI shows the specific failure. Fix. Read the response body for the field name; correct the podspec; retry. HTTP 422.
