Performing a rest call using Spring's RestClient locally works fine for me. I have problems executing that on my pod on my Kubernetes cluster:
private fun callApi() { log.info("Deleting device with $id") restClient .delete() .uri("${getBaseUrl()}/api/${getId()}") .headers { it.setBearerAuth(getToken()) } .retrieve() .onStatus({ obj: HttpStatusCode -> obj.isError }, ERROR_HANDLER) .toBodilessEntity() }This results in the following exception on my cluster. Do you have any idea where the error is coming from?
