401: Unauthorized (Warning: Invalid argument supplied for foreach() in /usr/src/grocytobring/GrocyApi.php on line 19)

When I install GrocyToBring I have authorization error.
Api call to objects/quantity_units return all time 401: Unauthorized, I need more explanation for configuration. Or it's an error to access to the API with PHP.

It sounds like you are using grocy as a Hassio addon. If so, the Ingress network will not grant access to the Grocy API w/o the Hassio credentials and will return 401: Unauthorized.
You need to go to Supervisor->grocy->Configuration. At the bottom of this configuration page you'll find "Network". Change the port to any unused port of your host (that will not destroy your Ingress network, it just opens an additional port for direct access to Grocy). Then restart the Grocy addon and modify the .env-file of GrocyToBring.
For example, if your Hassio device has 192.168.1.2 and you set port 12345 then enter GROCYURL=http://192.168.1.2:12345/api/

Hi,
I have the same problem here:

Warning: Invalid argument supplied for foreach() in /usr/src/grocytobring/GrocyApi.php on line 17

Warning: Invalid argument supplied for foreach() in /usr/src/grocytobring/GrocyApi.php on line 69

Warning: Invalid argument supplied for foreach() in /usr/src/grocytobring/index.php on line 33

This is a standalone grocy podman/docker container. I run this container on the same machine and have the the env set like this: GROCYURL=http://localhost:6666/api/

PS: Grocy shows: Version 4.2.0 if that's of use. Also the bring part seems to work, since I was able to extract all of my UUIDs of the lists I created to match the stores.
Also, I'm trying the SOURCE=shoppinglist version

update: I messed up the localhost part since the containers won't talk to each other that way? But setting the IP of the Server both containers are running on won't change anything either.

It certainly isn't the grocy API, since both calls (or three if using shoppinglist) work well with curl outside of the docker container
