Error when updating slots/sentences via HTTP-API

It was possible to update slots and sentences over the HTTP-API. I used this successfully for some time now.
Tried again and I always get an error.

curl -d '{"intents/Shortcuts.ini":"[Shortcuts]\ntest\n"}' -X POST http://localhost:12101/api/sentences -H "Content-Type: application/json"

BadRequest: BadRequest(400)

The Rhasspy Log tells me:

[ERROR:2021-02-17 15:11:02,350] rhasspyserver_hermes: BadRequest(400)

During handling of the above exception, another exception occurred:

Has there anything been changed recently or am I doing something wrong?

Thank you!

This seems to be completely my fault. I just don’t get what I’m doing wrong. Even when I’m writing the curl-command in the correct order, it doesn’t work.
