Description
OrientDB Version: 3.0.37
Java Version: 1.8
OS: Windows
Using a distributed database (2 or 3 nodes)
Expected behavior
The scheduler should be created with the command :
INSERT INTO oschedule
SET name = 'myEvent',
function = (SELECT FROM ofunction WHERE name = 'myFunction'),
rule = "* */1 * * * ?"
Actual behavior
With a standalone database, the OScheduler record is created correctly, and the task is started normaly.
With a distributed database, I get an error :
Error when creating the scheduler
java.lang.IllegalStateException: The current database instance (com.orientechnologies.orient.server.distributed.impl.ODatabaseDocumentDistributed@bc98660) is not active on the current thread (Thread[OrientDB HTTP Connection /127.0.0.1:2480>-/127.0.0.1:63380,5,OrientDB]). Current active
database is: com.orientechnologies.orient.server.distributed.impl.ODatabaseDocumentDistributed@5866e8c8
Is the scheduler working normaly in a distributed databese ?
Thanks for your help

Research direction
Reproduce the SQL INSERT on a two- or three-node distributed database using OrientDB 3.0.37, then compare it with the standalone behavior. Trace the scheduler creation failure reported for the distributed database and verify that the scheduler record is created and its task starts normally across nodes.
