Strange Json issue, conversion from QByteArray to QJsonDocument not working as intended

@DanBar said in Strange Json issue, conversion from QByteArray to QJsonDocument not working as intended:

"Json error: illegal number"
what does that mean?

possibly an integer/decimal value beginning with 0 (e.g. propertyName: 01234)? unless it's an octal value.

DanBar

@raven-worx There are many values that are 0 and a few values that are decimal, are those allowed while running in Qtcreator but not as an installed program?

a sample part of the json:
"name": "Test 4",
"valueA": 180,
"valueB": "",
"valueC": 9,
"valueD": 1,
"valueE": 0.8869204367,
"valueF": 1500,
"valueG": "C",
"valueH": 0,
"valueI": "16d29c44-3d0941",
"valueJ": "1392fa45-68c943",
"valueK": "2018-08-06 09:07:29",

Hi
You you also output
http://doc.qt.io/qt-5/qjsonparseerror.html#offset-var
as it gives a clue where in the file it gets error.

"valueK": "2018-08-06 09:07:29",

none of those values should raise this error as far i see.
I was talking about decimals bigger than 0. So 0 is of course a valid decimal value, but 02934 not

But you havent answered my first question. Are you sure you already received the full data before you start to parse the JSON data?!

Hi,

How long is the long array that makes things fail ?

See QTBUG-47629 for a limitation on QJsonObject's size.

Thank you all for your help!

I was able to solve this issue, but the problem wasn't in the Json itself. I got a tip a tip from my colleague to check the .dll-files in the installation folder, and I noticed that they weren't entirely up to date. When I replaced them with the correct version of .dll-files the issue was solved. I still don't know exactly what caused this issue between the versions (version 5.9 and 5.10) but the issue is solved so I'm happy in either case.

Again, thanks!

installation folder

Which installation folder do you mean? Qt? Your app?

DanBar

@jsulm Not the Qt folder, my own installation folder for the software I'm creating.

jsulm

@DanBar How do you create this installation directory? Qt provides tools for deployment.

DanBar

@jsulm we make an installation file for our combined system, including multiple programs sharing some but not other resources. we use an nsi script to manage this. usually works fine. I just missed updating some of the .dll files.
