reproduction

Its unclear how that is happening. It did happen only for our support user which did not have no client set. If that is the cause or a specific file filter config is unclear.

solution

Ensure that if $this->Php2JsVars()->get('supportedFileExtensions') contains no data / invalid data the application still loads and writes a meaningful error message.
