How to use a new Meilisearch API key?

[Ra72xx]

Because I changed my installation I also changed the Meilisearch API key. However, now if I try to access Wanderer web, I can no longer view my tracks. The log shows that Wanderer is using a wrong API key.

The environment variable is correctly set
MEILI_MASTER_KEY=my_key
and e.g. querying Meili with
curl -X GET localhost:7700/keys -H "Authorization: Bearer my_key"
also works.
I also let Linkwarden access the same Meili instance and the changed master key was only a change of the corresponding value in Linkwarden's settings.
Is there something else in Wanderer I have to change in Wanderer if the Meilisearch API key is changed?
