Media Manager error on loading main page from dashboard

[temporalFluid]

After a fresh error-free install of modx3-rc2, I installed mediamanager [BETA], configured it [as written on their github](https://github.com/Sterc/mediamanager), and then am confronted with this error on the media > media manager page:

Your default mediasource (ID 1) is not configured to use with the Media Manager. Please add a property 'mediamanagerSource' with value '1' to this mediasource and all other mediasources you want to use with the Media Manager.
I then triple checked the mediamanagerSource was set to 1 and that I added the property to the admin user and pointed it to the media source I'm using.

Finally, checking the error manager I am seeing the following errors:
[2022-02-24 17:47:42] (ERROR @ /home/******/public_html/core/vendor/xpdo/xpdo/src/xPDO/xPDO.php : 1340) Could not get table class for class: modMediaSource [2022-02-24 17:47:42] (ERROR @ /home/******/public_html/core/vendor/xpdo/xpdo/src/xPDO/xPDO.php : 1309) Could not get table name for class: modMediaSource [2022-02-24 17:47:42] (ERROR @ /home/******/public_html/core/vendor/xpdo/xpdo/src/xPDO/xPDO.php : 786) modMediaSource::getSelectColumns() is not a valid static method.

[2022-02-24 17:48:16] (ERROR @ /home/******/public_html/core/vendor/xpdo/xpdo/src/xPDO/xPDO.php : 786) modMediaSource::load() is not a valid static method.

So I went in phpMyAdmin and found the modx_media_sources to double check the new property was registered properly:
a:4:{s:8:"basePath";a:6:{s:4:"name";s:8:"basePath";s:4:"desc";s:23:"prop_file.basePath_desc";s:4:"type";s:9:"textfield";s:7:"options";a:0:{}s:5:"value";s:1:"/";s:7:"lexicon";s:11:"core:source";}s:7:"baseUrl";a:6:{s:4:"name";s:7:"baseUrl";s:4:"desc";s:22:"prop_file.baseUrl_desc";s:4:"type";s:9:"textfield";s:7:"options";a:0:{}s:5:"value";s:1:"/";s:7:"lexicon";s:11:"core:source";}s:15:"imageExtensions";a:6:{s:4:"name";s:15:"imageExtensions";s:4:"desc";s:30:"prop_file.imageExtensions_desc";s:4:"type";s:9:"textfield";s:7:"options";a:0:{}s:5:"value";s:25:"jpg,jpeg,png,gif,svg,webp";s:7:"lexicon";s:11:"core:source";}s:18:"mediamanagerSource";a:6:{s:4:"name";s:18:"mediamanagerSource";s:4:"desc";s:0:"";s:4:"type";s:9:"textfield";s:7:"options";a:0:{}s:5:"value";s:1:"1";s:7:"lexicon";N;}}
I'm stuck wondering how to address this error. how to move forward. I was very excited to try this addon, as the present mediabrowser does not jive with my clients needs.

Any feedback or request for more information truely appreciated!

I am also interested in a solution to this.

I reinstalled the MediaManager from scratch, that broke the error message. Instead of giving me an ID it now gives me "mediasource (ID [[+ mediasource_id]]"

During installation I got this error:

Could not load class: modTransportPackage from mysql.modtransportpackage Could not get table name for class: Error 42000 executing statement: Array ( [0] => 42000 [1] => 1064 [2] => You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'AS latestPackageWHERE latestPackage.package_name = modTra...' at line 3 ) PHP warning: Undefined array key "topic"

After digging around in this, it appears you HAVE to have the media source tied to an ACL. It doesn't work if you don't have a user group with media source ACLs because it is querying the database directly. Once I added my media source to a user group and assigned my user to that group, it started working.
