We use to be able to read data from an Oracle Synonym pointing to a table via a database link. But now we are getting a strange error and are unable to see the attributes any more.

Warning: Unable to use schema obtained for Oracle Spatial layer 'schema.table'

We are getting the same error from both "Oracle Autonomous Non-Spatial" and "Oracle Non-Spatial" that use to work before.

I have looked into this article https://community.safe.com/s/article/working-with-synonyms-in-oracle and executed the command on a test synonym without any luck. 

Have somebody else seen this issue before and have any knowledge of how to get it working again. We are not sure what happened, suggestions are much welcome.

The synonyms work just fine with normal SQL, it's just FME Desktop we see issues.

We are running Oracle 12.0.1 on Windows in a test/developer environment.

FME 2020.1.1.1 (20200817 - Build 20614 - WIN64)

FME Desktop Professional Edition 

Oracle 12.0.1 Client 64-bit - Administration

I see the same issue in FME Desktop 2019.2 and 2021 Beta.
