Summary of Changes

There's an inconsistency in the com_ajax logic that prevents modules resolving correctly the Helper file (read the testing instructions below). The proposed fix is to use a strtolower for the db name of the module and let the other parts intact...

Testing Instructions

To experience the bug you need to edit the file administrator/modules/mod_guidedtours/src/Helper/GuidedToursHelper.php and add on function named toursAjax ie:

    public function toursAjax()
    {
        return ["success" => true, "message" => "in a bottle"];
    }

Then in the cpanel open the browser console and run

await fetch(new URL(`${Joomla.getOptions('system.paths').baseFull}index.php?option=com_ajax&module=guidedtours&method=tours&format=json`), { headers: { 'X-CSRF-Token': Joomla.getOptions('csrf.token') } }).then(x => x.json())

Note: the part module=guidedtours (prefixed with mod_) reflects the column element in the #__extensions table.

The result is that the com_ajax will Look for a GuidedtoursHelper class, which will fail on any case sensitive filesystem:

Apply the PR and run in the console the following (observe that the module now is defined as GuidedTours)

await fetch(new URL(`${Joomla.getOptions('system.paths').baseFull}index.php?option=com_ajax&module=GuidedTours&method=tours&format=json`), { headers: { 'X-CSRF-Token': Joomla.getOptions('csrf.token') } }).then(x => x.json())

The class is correctly identified as GuidedToursHelper
