Urgent help needed: Value Streams not working

Hi,

I'm running Thingworx 8 server locally, my DB is Postgresql - Value Streams are exhibiting very odd behavior, when I create a value stream (using ThingworxPersistenceProvider), connect it to a thing & run QueryPropertyHistory - I get an error saying Data Store Unknown. Switched on stack trace and this is what I got:

2020-02-21 16:55:35.516+0400 [L: ERROR] [O: E.c.t.p.p.PostgresDataExceptionTranslator] [I: ] [U: Administrator] [S: ] [T: http-nio-8080-exec-8] [message: [1,018] Data store unknown error: [Error occurred while accessing the data provider.]] org.postgresql.util.PSQLException: ERROR: relation "value_stream" does not exist
Position: 32

------------------------

I'm also unable to delete any value streams, get an error saying unable to dispose.  When I look at the valuestream_model table in PGAdmin, it's empty, though they do exist in the thing_model table.

Try adding visibility permissions to the user who is executing the query.

Add it to Persistence Provider itself most likely it is already in place on the ValueStream itself (but double check)

Hello @Assembly ,

 

Here it suggests that you dropped the table with value stream data:

relation "value_stream" does not exist

 

What did you do before this error appeared?

Hi,

 

You need to have a "value_stream" table in the database. Does it contain data?

 

Thanks,
