Error codes
validation.parameter_missing
A required query or path parameter was not supplied.
validation.parameter_missing is returned at HTTP 400.
When this fires
Spring's MissingServletRequestParameterException. The endpoint declared a parameter without a default and the request omitted it.
What to do
Add the missing parameter — its name appears in errors[0].path. Re-run after fixing.
