Error storing tag history in Postgres database

I am using Ignition 8.1.25 version and PostgreSQL 15.2 (Debian 15.2-1.pgdg110+1) on x86_64-pc-linux-gnu, compiled by gcc (Debian 10.2.1-6) 10.2.1 20210110, 64-bit

I want to use database history provider but there are several errors in logs:


You should contact support. A NullPointException; the actual inner cause of the problem here, is always a programming bug on our part.

The reason was not in Postgres database. The reason was in the name of realtime tag provider. The tag provider was called like "Realtime. Tag. Provider". There was a full stops and spaces in the name. When I change name to the "Realtime_Tag_Provider" the problem was solved. And now values of the tags is storing in my database.
