Redis cache issue with CSS/JS assets generated by Spectra plugin

[danmaby]

Hey team, I see an issue with CSS and JS files generated by the Spectra plugin. The plugin has an option in its "Asset Generation" setting to generate external CSS/JS files rather than generating inline. Turning this setting on produces the following URLs for assets:

/wp-content/uploads/uag-plugin/assets/5000/uag-css-XXXXXX-XXXXXX.css

When Redis cache is enabled on the server and the above setting is turned on, CSS/JS assets are not loaded.

To reproduce:

1. Enable File Generation in Spectra "Asset Generation" setting
2. Click Asset Regeneration in Spectra "Asset Generation" setting
3. Purge all SpinupWP cache
4. View a page with a Spectra block in incognito/private - broken CSS/JS

To temporarily overcome this, I have disabled Redis Caching on the server

define( 'WP_REDIS_DISABLED', true );

It appears to be simial to this issue that was generated by Elementor.
