Hello all,
In our Ignition Perspective project, we've encountered a module error related to the JSON library. This issue is frequently triggering errors that are flooding our gateway logs.
The Error is Below:
Traceback (most recent call last): File "<function:runAction>", line 3, in runAction File "/usr/local/bin/ignition/user-lib/pylib/json/__init__.py", line 108, in <module> from .decoder import JSONDecoder File "/usr/local/bin/ignition/user-lib/pylib/json/decoder.py", line 24, in <module> NaN, PosInf, NegInf = _floatconstants() File "/usr/local/bin/ignition/user-lib/pylib/json/decoder.py", line 18, in _floatconstants _BYTES = '7FF80000000000007FF0000000000000'.decode('hex') LookupError: unknown encoding 'hex'

If Anyone has encountered this issue before, please share your insights or solutions. Your assistance would be greatly appreciated.
Thanks.
Well... How about you show us the code ?
And not just an image of the code. Format it properly.
PS: Don't ping people.
The code in Import json that is,
What happens if you try to import it from somewhere else ?
If i try to import json in script console it will through the below error,
Traceback (most recent call last): File "function:runAction", line 1, in runAction File "/usr/local/bin/ignition/user-lib/pylib/json/**init** .py", line 108, in from .decoder import JSONDecoder File "/usr/local/bin/ignition/user-lib/pylib/json/decoder.py", line 24, in NaN, PosInf, NegInf = _floatconstants() File "/usr/local/bin/ignition/user-lib/pylib/json/decoder.py", line 18, in _floatconstants _BYTES = '7FF80000000000007FF0000000000000'.decode('hex') LookupError: unknown encoding 'hex'
Don't use json from jython's stdlib. Use Ignition's system.util.jsonDecode() and/or system.util.jsonEncode() functions--these are documented and supported.
Please see Wiki - how to post code on this forum. Use this when posting code or error messages. Thanks.
Okay, @pturmel Thanks for your Reply.
