Query error logs for Google Workspace add-ons

When a published Google Workspace add-on returns an error, the add-on interface returns a generic message of "Something went wrong when executing the add-on." However, these errors are logged to Cloud Logs Explorer.

This guide describes how to query add-on error logs in Cloud Logs Explorer, so you can:

• Learn if users encounter errors.
• See how often errors occur, and which are most frequent.
• Read descriptive error messages that help you fix them.

Prerequisites

Before querying add-on error logs:

• Enable the "Cloud Logging API" in the add-on's Google Cloud project. To enable an API, refer to Create a Cloud project and enable the API.
• Publish the add-on on Google Workspace Marketplace. To publish an add-on on the Marketplace, refer to Publish an app.

Query add-on error logs

To get logs for an add-on:

1. Open the Google Cloud console.
2. Next to "Google Cloud Platform," click the Down arrow arrow_drop_down and select the add-on project.
3. In the top-left corner, click Menu menu > Logging. The Logs Explorer opens.

4. For add-on error logs, in the query builder, enter the following query:

   severity>=ERROR
   protoPayload.serviceName="gsuiteaddons.googleapis.com"
   

5. To see recent errors, click Run query. Or, to see errors as they occur, click Stream logs. Add-ons error logs appear in the "Query results" pane.

For further information about Cloud Logs Explorer and writing queries, refer to the following:

• Use the Logs Explorer
• Build queries

Enable or disable error logging

By default, error logging is enabled. When error logging is enabled, the manifest file has the following:

"exceptionLogging": "STACKDRIVER",

To disable error logging, replace "exceptionLogging": "STACKDRIVER", with the following line in the manifest file:

// Disable error logging
"exceptionLogging": "NONE"

To re-enable error logging, replace "exceptionLogging": "NONE" with "exceptionLogging": "STACKDRIVER",.

Considerations

As you work with add-on error logs in Cloud Logs Explorer, take note of these considerations:

• Add-ons only log errors in Logs Explorer. Other log types are not recorded.
• Error messages are always written in English.
• Cloud Logging incurs a cost. For further information about Cloud Logging pricing, refer to Google Cloud Observability pricing.
