Workers object not returned in /describe endpoint response, although /workers/describe endpoint work

I am trying to get all the objects supported by a user with /describe endpoint and getting the metadata individually for each object. However, the /describe endpoint gives data till journeyCategoriesLOV and does not give the data after that.

However, if I try to get the data for workers, I am able to the data. Also, metadata is acccessable through /workers/describe endpoint.

What needs to be done so that we get Workers object in /describe call?
