I hit this error as well. I wrote a Python script (below) to automatically hack all the JSON files to be version 1.1 instead of 1.2.
After editing any source code, but before recompiling (either in VS2022 or using Live Coding), I always run my Python script (below) from my <project_root>/Intermediate/Build/Win64 directory.
My python script (I called it fix_json.py):
import os, fnmatch
def findReplace(directory, find, replace, filePattern):
for path, dirs, files in os.walk(os.path.abspath(directory)):
for filename in fnmatch.filter(files, filePattern):
filepath = os.path.join(path, filename)
print(filepath)
with open(filepath) as f:
s = f.read()
s = s.replace(find, replace)
with open(filepath, "w") as f:
f.write(s)
findReplace(".", "Version\": \"1.2", "Version\": \"1.1", "*.json")
