[SOLVED] WUA scan failure: JSONDecodeError

[t.heroult]

Hello everyone.

When running a WUA scan on a Windows 7 Pro machine (on which it had worked fine until now), the scan immediately fails with this message:

Code: Select all

JSONDecodeError: Expecting value: line 1 column 1 (char 0)
Traceback (most recent call last):

Any idea what might happen?

No idea?

It appears to be a corrupted waptwua_rules.json file (which is not actually a JSON file)

present

Code: Select all

C:\Program Files (x86)\wapt\private\persistent\?\waptwua_rules.json

Hello,

the problem has finally disappeared on its own.
