New Addon template tags breaks entry preview

[acutedeveloper]

Description of the problem

I have created a new template tag by create a new Addon using the eecli and then setting up new template tag using the make:template-tag.

The template tag will output its content fine in the websites templates. However when editing entries in the control panel, the preview pane presents this error:

ExpressionEngine\Service\Addon\Exceptions\ControllerException Caught

Invalid Module request! Are you sure \addonDeveloper\TemplateTag\Actions\Output is setup properly?

ee/ExpressionEngine/Service/Addon/Module.php:72

What testing I have tried

I have created a vanilla addon simply called template tag. I have setup a template tag within that addon with an output method.

This is the content of the Tags/Output.php file

<?php

namespace AcuteDeveloper\TemplateTag\Tags;

use ExpressionEngine\Service\Addon\Controllers\Tag\AbstractRoute;

class Output extends AbstractRoute
{
    // Example tag: {exp:templatetag:output}
    public function process()
    {
        return "My tag";
    }
}

In the frontend templates, it outputs fine. In the control panel previews, the error above is presented.

My setup

• EE 7.2.6
• Using structure templates
• Testing on my local laravel valet environment

I have a _base.html file that is extended by templates in a layout folder.

layouts
     - _base.html
     - _homepage.html

How To Reproduce

1. Ensure you have templates that you can preview in the entries preview pane
2. Create a new Addon with make:addon.
3. Create a new template tag with make:template-tag.
4. Add your new template tab to your template
5. Preview the template in a new entry
6. Error presented

Possible Solution
For now Im trying the older pi.addon_name.php plugin file style.

@acutedeveloper thank you for reporting this!

Because Live Preview is action request, the Addon service is looking in the wrong place. We'll try to get this fixed in next patch release
