What fixed it 

New driver from: https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html

cd /lib/firmware

What was wrong? It needed a new device driver from Intel (thanks Intel!) and the renaming had to be shut off (thanks https://forums.linuxmint.com/viewtopic.php?t=303841)

This took many hours - I hope you find it helpful. :)

The firewall refused all the stuff and I am way too tired to deal with it ... here's a screenshot

ibexa - stimulus - webpack

It's 4:20a - please excuse this post ...

I wanted to use the ibexa REST API to dump the content types

So - I needed to add some JavaScript. Stimulus was there, so I figured I'd use it. It's cool.

I haven't worked with this stuff ... ever

I had to upgrade webpack or encore or something

Which identified path issues in the ibexa CSS and SCSS

I was hoping it would be quicker to fix the issues than ... not fix them, so I tried and am posting the results here so that eventually I can fork the repo and make a proper pull request

If you're looking for a rough example of working with Stimulus, Symfony and the Ibexa REST API - https://github.com/bgamrat/improved-journey/commit/c2ee360c8167395e4a1d5af7992ea1e0bf921124

If you found this helpful - yay :)

Also - I had to reset my password for this blog for the umpteenth time ...

mod_proxy_ajp declining URL

Many hours of searching and suffering were spent trying to resolve this ...

Apache-Error: [file "mod_proxy_ajp.c"] [line 743] [level 7] AH00894: declining URL fcgi://localhost/var/www/html/site/public/index.php

This is a Symfony application (ibexa DXP, formerly eZ Platform, previously eZ Publish), CentOS 8 server, with PHP 7.4, mod_security, selinux enabled, etc.

The error was thrown on the graphql requests to support the sub-items display of the admin interface.

The root cause of the issue was an application error.

The message from Symfony

[2022-01-05T18:34:58.709826+00:00] request.CRITICAL: Uncaught PHP Exception Overblog\GraphQLBundle\Resolver\UnresolvableException: "Could not found type with alias "RepositoryLanguage". Do you forget to define it?" at /var/www/html/site/vendor/overblog/graphql-bundle/src/Resolver/TypeResolver.php line 72 {"exception":"[object] (Overblog\\GraphQLBundle\\Resolver\\UnresolvableException(code: 0): Could not found type with alias \"RepositoryLanguage\". Do you forget to define it? at /var/www/html/site/vendor/overblog/graphql-bundle/src/Resolver/TypeResolver.php:72)"} []

This also took me a long time to unravel - about an hour ... because I haven't worked with eZ in a while

Solution was to copy all these files https://github.com/bgamrat/improved-journey/tree/main/config/graphql/types/ezplatform into the config.

Next, it was time to make this blog post with the goal of helping you!

I changed the username for security, to a word I rarely use. So of course I forgot it. As well as the password. Tried to email a password reset, but that failed too ... selinux, remember?

setsebool -P httpd_can_sendmail 1

I also tried to reset the password at the database level, but that looked like more effort.

So - it was a grand adventure, the installation works and I can go do other things.
