Description

Dear PySim Team,

either my Syntax is wrong, or the Json Path function is not working correctly for changing the K, OP and OPC values in the USIM_AUTH_KEY folder. If possible, please give me a hint what the correct syntax would look like, I tried multiple syntax' that only produced exception errors.

I tried the JSON Path example from the readme.MD (target: OFM), that is working just fine for me, but it is a boolean value and therefore the syntax is not 100% applicable to the OPC which looks like a string value.

I'm looking forward to hearing from you.

Kind regards,
Christoph Reimann
