EF6.4 error occurs in Poland, not UK

[brahmsproject]

We encounter a problem inserting a record into a PostgreSQL database via EF 6.4 - only when running a project in Poland. We do not get the error in the UK with exactly the same record. Below the Error log is the EF log. These logs are in Polish as submitted by that project.

from application error log:

Message :An error occurred while updating the entries. See the inner exception for details.

@brahmsproject the non-core EF 6 provider is no longer being actively maintained.

In any case, the error message seems to be about a syntax error at or around = (equality), but the INSERT SQL you quoted doesn't contain that... I'm guessing maybe you quoted a SQL that's different from the one that actually caused the problem?
