[Looker API] No models even with "see_lookml" Permission Set

Hi,

I am new on Looker API dev. I am trying to access my LookML models without success using:

sdk.all_lookml_models()
sdk.lookml_model(“xyz”)

The first one returns an empty array and the second one returns 404 Not Found. I confirmed the model name for the same SDK user. I can see the model and run all Explores. I confirmed the user has “see_lookml” permission set.

I can use sdk.look( look_id= “33” ) and sdk.all_dashboards() with no issues.

Any clues what can be wrong?
Thanks.
