TYPO3 Mask asks for EXT:example_extension

Question

I am new to the TYPO3 Mask extension. I have Typo3 9.5.18 and Mask 4.1.2, both installed via composer.

I have adapted all paths to my site package.

When I select Mask -> Page Template, I get

(1/2) #1509741912 TYPO3Fluid\Fluid\Core\ViewHelper\Exception Supplied file object type null for EXT:example_extension/Resources/Public/Images/BackendLayouts/default.gif must be File or FileReference.

Looks like mask expects an extension example_extension. Where can I change this to match my site package?

Answer 1

You can change these settings under Admin Tools > Settings > Extension Configuration > Mask.

These settings are stored in your LocalConfiguration.php in an array (EXT > extConf > mask)

General

Frontend

Backend

Answer 2

Thanks for the answer. I had all paths already configured the way you suggested. The real reason was a bit more involved: I had mask installed on a project that already had a few backend layouts. These backend layouts had been generated by the List module and been copied into a *.ts file.

The list module generates the following line in the backend layout:

icon = EXT:example_extension/Resources/Public/Images/BackendLayouts/default.gif

As my site package is called virus, example_extension is not really a match here.

TYPO3 just displays a red icon in this case. Mask seems to be a bit more picky and runs into the described error.

So I'll be careful when migrating a project to mask.
