Hello, I've tried to install your extension by documentation.

composer require sintra/pimcore-webhooks:dev-main

part was successful, but installation from the admin panel ("Bundles & Bricks") gives me an error:

Hey! I experience the same Problem since you're extending a MigrationInstaller class in WebHookBundleInstaller.php.
I couldn't find any MigrationInstaller class so far.
How to provide this behaviour?
I have exactly the same output as @Hubbitus

[zeppaman]

the main branch is for PimcoreX, the Pimcore-6 is the one for Pimcore 6. Are you sure to be using the right one for your project?

[Hubbitus]

@zeppaman, please look, required sintra/pimcore-webhooks:dev-main and used pimcore pimcore/demo:10.0.6. Are that incorrect set of versions?

[MarcoMisiani]

Hi Hubbitus, that set of version is correct, try to disable the bundle and run: composer update "sintra/pimcore-webhooks" and then enable/install again

[Hubbitus]

Maybe then it require provide some specific version?
