Cannot import extensions into Thingworx8.4.1
Hi,
I'm trying to import extensions into Thingworx8.4.1 but found below errors:


I followed the PTC install guide to manually create thingworxplatform folders and the platform-settings.json:


After I installed the 8.4.1, I found another 3 folders were created and another platform-settings.json file here:


Once I trying to add the "extension policy" parameters to the second json file, I cannot connect to thingworx. In fact, once I modified anything in the second file, I cannot connect.
Does anyone know what's going on?
how am I be able to import the extensions?
Thank you so much!
