update command not working for PSQL database

Hello,

i just switched from H2 to postgreSQL database, my process was working fine, but after the migration it faced some errors!

it seems that my process is able to connect, and read data, but he is unable to perform any INSERT request to the database (i guess UPDATE as well).

Is there a particular action that i need to do in order to allow the insert/update? if yes, could you please lead me to the respectful page?

thank you
