unable_to_write_batch in db connect add-on

Explorer

when installing and configuring the add-on, the following problem occurred.

java.io.IOException: HTTP Error 400: Bad Request

I use Splunk DB Connect 3.1.3 with jre1.8.0_181 and postgresql JDBC driver in Windows Operation system.
When I test my SQL query with the db-connect SQL Explorer, I get the correct data from my PostgreSQL database.
When I use input with rising or batch I get this HTTP Error

I had the same error with DB Connect 3.1.4, jre1.8.0_201 and postgres jdbc 42.2.5

Querying the data with dbxquery is no problem, also was the definition of the input. But each execution, the error appears.

Update: I tried a Teradata Express with terajdbc4 16.20.00.10. Same error

Re: unable_to_write_batch in db connect add-on

Path Finder

Http Event Collector expects to receive dates in the format:

timestamp.microsecondes

Splunk DB connect transforms dates in this format via Java. If the default locale takes the comma as the decimal separator, the problems start ...

To solve this problem :

In Splunk DB Connect > Configuration> Settings> General, add the option in JVM Options:

-Duser.language=en

Save, java server restarts.
