Could I avoid the problem by using a MySQL database? Until now I did not used the objects endpoint as it does not provide PUT.
In the meantime, I also found why my code was sending requests in parallel: I forgot an await.
But how could I recover from a locked database in future? Because parallel requests are also possible (but not very likely) when two users are changing the tree at the same time.
Gramps Web doesn’t support MySQL. It support Postgres, but for a handful of users this is usually not needed. I run my own tree with SQLite and never have problems – as long as the tools interfacing with the API don’t send exactly simultaneous requests.

I honestly don’t know. Would be good to find out for sure…
