Hi, sadly I need to switch to graphql as well.
In the REST API I could just request all locations.
In Graphql if I request inventoryItems including inventoryLevels including location, I get the message that I need to have access to read locations. While I just can do this in the REST API
Also, there is not just a simple request to get the locations.
Apologies but what exactly are you asking here? This sounds more like a statement more than a question?
If you could expand on what you need help with, the community can assist

How can there be a difference in access scopes between rest api and graphql?
