Troubleshoot failed triggers

Troubleshoot failures of your registered triggers in the Harness platform.

You can troubleshoot failures of your cURL or webhook initiated triggers in the Harness platform.

After a trigger runs, you can use the Trigger Explorer to troubleshoot cURL or webhook initiated failures. For cURL, you enter the eventCorrelationId from the response. For webhooks, you enter the data value from the webhook response payload.

Troubleshoot webhook failures

To troubleshoot webhook failures, do the following:

cURL trigger

1. Open your Harness pipeline in Pipeline Studio.

2. Select Triggers.

3. Select Trigger Explorer.

4. Select Webhook.

5. In Enter Event Correlation id, enter the eventCorrelationId value from the cURL response payload.

6. Select Search.

   Harness returns the following information:

   • Event Correlation Id

   • Trigger Name

   • Trigger Status

   • Message

   • Payload

cURL example

Sample cURL command

~ % curl -X POST -H 'content-type: application/json' --url 'https://app.harness.io/gateway/pipeline/api/webhook/custom/v2?accountIdentifier=<YOUR_ACCOUNT_ID>&orgIdentifier=default&projectIdentifier=CD_Docs&pipelineIdentifier=tweety&triggerIdentifier=Custom' -d '{"sample_key": "sample_value"}'

Sample response

{"status":"FAILED","data":{"eventCorrelationId":"64e3e215d2bb844cfab9e155","apiUrl":"https://app.harness.io/gateway/pipeline/api/webhook/triggerExecutionDetails/64e3e215d2bb844cfab9e155?accountIdentifier=<YOUR_ACCOUNT_ID>","uiUrl":"https://app.harness.io/ng/#/account/<YOUR_ACCOUNT_ID>/cd/orgs/default/projects/CD_Docs/deployments?pipelineIdentifier=tweety&page=0","uiSetupUrl":"https://app.harness.io/ng/#/account/<YOUR_ACCOUNT_ID>/cd/orgs/default"}}

In this example, you enter the eventCorrelationId value in the Search field.

Webhook trigger

1. Open your Harness pipeline in Pipeline Studio.

2. Select Triggers.

3. Select Trigger Explorer.

4. Select Webhook.

5. In Enter Event Correlation id, enter the data value from the webhook response payload.

6. Select Search.

   Harness returns the following information:

   • Event Correlation Id

   • Trigger Name

   • Trigger Status

   • Message

   • Payload

Webhook example

The pipeline below runs when a repo has a PR.

This example uses the tweety repo.

Sample pipeline URL

https://app.harness.io/ng/account/\<YOUR_ACCOUNT_ID>/cd/orgs/default/projects/CD_Docs/pipelines/tweety/executions?storeType=INLINE

Sample response

{"status":"FAILED","data":"64e3e5b58cdd8704d75bd99d","metaData":null,"correlationId":"1a75bbef-862c-469e-b8ab-e06dd95e4999"}

In this example, you enter the data value in the Search field.
