Cause

An installed app is incompatible with the new Bitbucket version

The issue is caused by an unsupported third-party app, File Hooks Plugin. It’s possible that this app was working with Bitbucket version 7.21.7, but is no longer compatible with Bitbucket latest versions of Bitbucket, such as 9.4, and hence the problem started after the Bitbucket upgrade.

Solution

Disable the File Hooks Plugin via Settings > Manage Apps, and then attempt the push again.
