@ajanth97 thanks for finding/reporting this! I think the error comes from here, where we're not checking if the type assertion worked. In fact, we're doing a similar thing here: https://github.com/kedacore/http-add-on/blob/main/interceptor/forward_wait_func.go#L41. In the latter case. I'll submit a PR to fix both.
