Exception in DeeplTranslationService: Call to a member function listGlossaries() on null

[typoworx-de]

We have on a dev/live system similar issue. Sometimes for some reason this happens (even though deepl works usually).

As protected ?Translator $translator = null; is declared nullable, you should never expect trustfully that the service is available.

You should harden the code here:

    public function listGlossaries(): array
    {
        return $this->translator?->listGlossaries() ?? []];
    }

Pay attention to the comment:

    /**
     * Gets information about all existing glossaries.
     *
     * You can call this method only if "isAvailable()" returns true.
