Freematics compiling error

I just bought 2 freematics traccar edition trackers. I get an error during compiling the code. This is with freematics builder 1.2.3 V5 telelogger

Error occurred during compiliation

Are you using the steps from the documentation?

https://www.traccar.org/freematics-configuration/

Well except I downloaded the freematics builder exe instead of using the Visual studio code because that didnt work.

Are you saying both didn't work?

Also config.h cannot be edited (reverts back to default every time). Config.xml is the one that changes the configuration.

Freematics builder produces a compiler error.

Visual studio code is to create the freematics builder. There is no instructions on what to do after platformIO has been installed. For example what board needs to be selected?
