Troubleshoot

If your application errors are not showing up in Error Reporting, then use the following steps to troubleshoot.

Before you begin

Verify that Error Reporting can analyze your log entries.

Error Reporting is a global service built on Cloud Logging and can analyze log entries when all of the following are true:
- Assured workloads are disabled. For more information, see Overview of Assured Workloads.
- Customer-managed encryption keys (CMEK) is disabled on all log buckets that store the log entry. For information about how to determine the CMEK configuration for a log bucket, see Verify key enablement.
- The log bucket satisfies one of the following:
  - The log bucket is stored in the same project where the log entries originated.
  - The log entries were routed to a project, and then that project stored those log entries in a log bucket that it owns.
If you are storing your log entries in log buckets with CMEK enabled, then you can still use Error Reporting. However, you must use the Error Reporting client libraries or the Error Reporting API. For more information, see the Error Reporting API overview and Error Reporting client libraries.

To see a list of sinks you have configured, run the following command:
```
gcloud logging sinks list
```
The command returns an output similar to the following:
```
NAME               DESTINATION                                                                                                FILTER
_Default           logging.googleapis.com/projects/my-team-project/locations/global/buckets/_Default                          NOT LOG_ID("cloudaudit.googleapis.com/activity") AND NOT LOG_ID("externalaudit.googleapis.com/activity") AND NOT LOG_ID("cloudaudit.googleapis.com/system_event") AND NOT LOG_ID("externalaudit.googleapis.com/system_event") AND NOT LOG_ID("cloudaudit.googleapis.com/access_transparency") AND NOT LOG_ID("externalaudit.googleapis.com/access_transparency")
_Required          logging.googleapis.com/projects/my-team-project/locations/global/buckets/_Required                         LOG_ID("cloudaudit.googleapis.com/activity") OR LOG_ID("externalaudit.googleapis.com/activity") OR LOG_ID("cloudaudit.googleapis.com/system_event") OR LOG_ID("externalaudit.googleapis.com/system_event") OR LOG_ID("cloudaudit.googleapis.com/access_transparency") OR LOG_ID("externalaudit.googleapis.com/access_transparency")
logs-from-samples  logging.googleapis.com/projects/my-team-project/locations/global/buckets/sample-bucket                     (empty filter)
regional_logs      logging.googleapis.com/projects/my-team-project/locations/europe-west1/buckets/bucket_for_regional_logs    (empty filter)
test-logs          logging.googleapis.com/projects/team-b-project/locations/global/buckets/test-bucket                        (empty filter)
```
In this example, the source Google Cloud project of the log entries is my-team-project. As a result:
- Error Reporting can analyze the log entries routed by the _Default, _Required, and logs-from-samples sinks because the log bucket is stored by the same project that routes the log entries.
- Error Reporting can't analyze the log entries stored in the log bucket named test-logs because the sink in my-team-project routes the log entries to a log bucket in a different project.
Ensure that you have the Google Cloud CLI installed.
Ensure that you have the beta component enabled for the gcloud CLI.

When using logs

This section provides troubleshooting support when your error data is written to Cloud Logging buckets, and you rely on Error Reporting to automatically analyze those log buckets.

Generate a sample log entry

To confirm your project settings, you can programmatically generate a log entry that will be picked up by Error Reporting with the following gcloud command:

gcloud logging write --payload-type=json test-errors-log \
  '{"serviceContext":
    {"service": "manual-testing"},
    "message": "Test Error\n at /test.js:42:42",
    "context": {"httpRequest":
      {"url": "/test","method": "GET","responseStatusCode": 500}}}'

Then open Error Reporting and confirm that you see the newly created error.

Confirm the log entry format

Navigate to the Cloud Logging page and locate a log entry that contains exception data sent from your application.

Confirm that the log entry uses the expected format.

When using the Error Reporting API

Enable the required API.
Enable the API

Send a test error

Try sending an error to the service manually.

You can report a test error to Error Reporting using the following gcloud command:

gcloud beta error-reporting events report --service Manual --service-version test1 \
  --message "java.lang.TestError: msg
    at com.example.TestClass.test(TestClass.java:51)
    at com.example.AnotherClass(AnotherClass.java:25)"

You can use a cURL command to test your REST API calls. Replace PROJECT_ID and API_KEY with your valid values before sending the following command:

curl -X POST -H "Content-Type: application/json" \
  -d '{"message":"java.lang.TestError: msg\n\tat com.example.TestClass.test(TestClass.java:51)\n\tat com.example.AnotherClass(AnotherClass.java:25)","serviceContext":{"service":"manual-testing"}}' \
  https://clouderrorreporting.googleapis.com/v1beta1/projects/PROJECT_ID/events:report?key=API_KEY

Confirm the sent payload

Ensure that your application is sending exception data to the API in the correct format and that it contains the required attributes.

A stack trace is logged but not recognized by Error Reporting

You log an error by using the message field of a jsonPayload, and you expect Error Reporting to capture the error. However, the error data isn't captured.

To resolve this failure, try the following:

Ensure that the jsonPayload doesn't include a stack_trace or exception field. When those fields are present, the message field isn't evaluated.
Ensure that the structure of the stack trace is in one of the supported programming language formats. The stack trace isn't captured by Error Reporting when an unsupported format is used.
