modules/openapi-generator/src/main/resources/protobuf-schema/model.mustache row 32 update
{{#vendorExtensions.x-protobuf-type}}{{{.}}} {{/vendorExtensions.x-protobuf-type}}{{enumName}} {{name}} = {{vendorExtensions.x-protobuf-index}};

Start with modules/openapi-generator/src/main/resources/protobuf-schema/model.mustache around line 32 and review related issue #14892. Check how the provided array-of-enum declaration is rendered by the protobuf-schema model template. Done means the generated model correctly supports the clientList array enum case.
