3.2 JSON Parse error: Unrecognized token '<' Password bug
-
This is what I have on the SD card, and a search of the file names turned up nothing. I could be looking in the wrong place though, since I have no clue where those files sit, or how to modify them.
-
@chrishamm said in 3.2 JSON Parse error: Unrecognized token '<':
The JS files are bundled by Webpack into very few files to accelerate the initial page load.
I don't know what this message from @chrishamm means.
I'm guessing that when the firmware is built a bunch of these files get packed together somehow, renamed and put somewhere on the Duet.
Sorry I'm not better versed in the Internets-part of 3D printing.
-
Neither do I.
No worries! You've been super helpful, and way more knowledgeable than myself! I greatly appreciate your time.
Since changing the browser or removing the password GCode fixed this issue, Im super happy.

Hello Guys,
have the same Problem.
Updated to the latest RFF Version since 2-3 Days and now i always get this error!I already uploaded the whole ZIP file again, deleted all gcodes files on the Duet Webinterface but nothing works.
Created also a new Thread here:https://forum.duet3d.com/topic/21024/json-error-and-connection-drops/4
I am using Google Chrome and get this error, so i think it is not a Browser Problem..
Kind Regards

@xenon2008 do you happen to have a m551 in your config setting a password. The last person who was having problems removed it and it worked. Wonder if there is an issue with passwords.
-
hmmm thats an idea, i really had an password in my DWC!
i will try this as soon as i'm at home at the printer!
Thanks alot! -
Good Evening,
sorry for the late Reply, but i must work every Day so long..
i now have commented out the Passwort in den config.g and rebooted my Duet 2 Wifi.
Currently i run a testprint, and have a look, but until yet it looks good. I hope it stays that way!But if so, what i or we can do, so that i can use a Password Protection without any Errors?
-
Did your password contain any special characters? Can you test a simple password?
-
@Phaedrux
No it is only a lowercase Word, nothing special -
Good Morning!
Since i have uncommented the Password Line in the config.g it seems to work?
How can i report this as a Bug?
-
@xenon2008 Consider it reported. Thanks.
@chrishamm will be glad you were able to replicate it.
-
I'm sorry but I'm having trouble reproducing this issue. It's all working as expected on Windows (Firefox), Linux (Chromium), and OS X (Safari). Can you confirm that you are using RRF 3.2 and DuetWiFiServer 1.25?
-
@chrishamm
Yes i can Confirm:
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.2 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2021-01-05
Tested with Google Chrome in Windows 10 x64 & on a Android Phone.

Hi,
I'm running 3.2 on a Duet 3 Mini 5
I didn't have M551 so I added it and rebooted.
DWC came up, asked for PW, entered PW - no issues.
I removed M551 and rebooted.
DWC came up - no issues.
Using most recent Chrome.

@xenon2008 can you provide the actual config.g that provokes the error? Maybe there's a special character or something in there.
-
Sure, should i PM this?
-
if you're concerned about sharing the password, sure. You can zip it up and email it to jason@duet3d.com

Hi, i am again!
Is it possible that its a PrusaSlicer issue?
I send the GCODE direct from PrusaSlicer to the Duet, and then i get this error if i click on "Jobs".I also tried to give a simple Name like Test.gcode to Upload to the DWC, with no other caracters...
-
Hi i am again,
It really looks like the Error comes from PrusaSlicer....
I have now updated to the latest Version from PrusaSlicer (2.3.0) but it is the same.
If i upload the Gcode direct from the Slicer i get the Error on the Webinterface.
BUT if i see this right, i get this error only then when the Passwort for the DWC is active, without i get no error until yet.So we have now to find out, if this is a PrusaSlicer or a DWC behavior.
Each time i upload a Gcode, also i have a dissconnect and a reconnect on the DWC, but without a Passwort dialog, even when the Password protection is enabled:
Hope this helps a little bit.
Kind Regards from Austria

Hello together!
Is there any Update?
I made also a Thread on Github on the PrusaSlicer Page.
