Issue

The following error occurs during deployment when upgrading to a version that supports PHP 8.1.

{{E: Error parsing configuration files:

at <script>:109:12
throw("The \"" + unsupported_extensions[0] + "\" extension is not supported for " + service.type);

E: Error: Invalid configuration files, aborting build}}

Cause

PHP 8.1 already includes JSON support and doesn’t require the extension to be installed separately.
