Error handling for DQL query client

s_eilmsteiner — Thu, 20 Apr 2023 07:37:36 GMT

Hi,
I fetch data via DQL using the queryExecutionClient from @dynatrace-sdk/client-query and I want to handle errors correctly. I know that there is the ErrorResponseDetails, but I don't know how to extract it.

import { ErrorResponseDetails, queryExecutionClient, QueryResult, } from '@dynatrace-sdk/client-query'; ... queryExecutionClient .queryExecute({ body: { query, requestTimeoutMilliseconds: 30000, }, abortSignal, }) .then((response) => { setResult(response.result); setError(undefined); }) .catch((error) => { // How can I get the ErrorResponseDetails }) .finally(() => { setLoading(false); });

Hi s_eilmsteiner,

You could try using the util function "isClientRequestError" with the desired type of error or "isErrorEnvelopeError". It depends on the expected error.

import { queryExecutionClient, ErrorResponseDetails, isClientRequestError, isErrorEnvelopeError } from '@dynatrace-sdk/client-query';

await queryExecutionClient.queryExecute({ ... }).catch((e) => {
  if (isClientRequestError<ErrorResponseDetails>(e)) {
    console.error('ErrorResponseDetails', e);
  }
  // OR
  if (isErrorEnvelopeError(e)) {
    console.error('EnvelopeError', e);
  }
});
