Webhook fails without an error message

Summary

The webhook fails without an error message when the webhook payload exceeds the limitation size of 256 KB. 

Environment

Bitbucket Cloud

Diagnosis

When triggering a webhook with a payload larger than 256 KB, the webhook fails silently without displaying any error message.

The Bitbucket team is aware of this behavior. There is already a feature request to improve the error message in this situation.  

Limit/warn when reaching the limit or raise the value for webhook description size of 256 KB

Please vote for the feature request if this behavior affects your service. 

Cause

The cause of this behavior is that Bitbucket Cloud has a limitation of 256 KB for the webhook payload. You can see this limitation on Troubleshoot webhooks page.

The Bitbucket commit is part of the Webhook payload. You may experience the issue when the Bitbucket commits message is bigger than 256 KB.

Solution

Decrease the commit messages to a size smaller than 256KB.
