On Azure Databricks, I have been creating AutoML experiments on May 15th 2026, using a Single User compute with Databricks runtime 17.3 LTS for ML, which I have assigned to myself.

I try to register one of the trained ML models in a schema, under a unity catalog, using the Databricks web UI.

However, no model is registered. A placeholder with the assigned model name gets created in the schema under Models, but no model version is registered.

This procedure was working two weeks ago.

I have ran the following SQL command
SHOW GRANTS `your_email@domain.com` ON SCHEMA <your_catalog>.<your_schema>;
and I verified I have CREATE MODEL permissions on the specific schema.

I have also ran the following SQL command
SHOW GRANTS `your_email@domain.com` ON CATALOG <your_catalog>;
and I verified I have both USE CATALOG and USE SCHEMA permissions on the specific catalog.

If I try to register the model using MLflow, it succeeds.

Why is this suddenly happening?
