Postgress - two phase commit does not supported

Hi everyone,

I'm trying to run a simple process that search a businessData object with a request like this:
Operation : searchResult [BusinessData] take the value of MyBusinessData.findByPersistanceId

The request of MyBusinessData.findByPersistanceId is :

SELECT c
FROM cDocument c
WHERE c.persistenceId= :persistenceId

When i'm running this process, I've got this error:

I have added the 'max_prepared_transactions = 100' in the postgresql.conf and set the 'max_connections' to 100 too.
When I'm running the command : 'show max_prepared_transactions;' in my DB, that's return '100'.
So, my posgres configuration seems like good.

And my postgres version is :
"PostgreSQL 10.4 on x86_64-pc-mingw64, compiled by gcc.exe (Rev5, Built by MSYS2 project) 4.9.2, 64-bit"

Someone can help me to fix this issue?
