till now I didn't perform any logic for it i'm just trying to print on the server response but i keep getting the same error message
when I figured it out it was because of an error on the controller function of that specific endpoint, and this is what I have tried to print but I keep getting the same error above, i know it's because of that endpoint function but I don't know what exactly

[error on the terminal]
i even have tried this but same error

any solutions? or why is this happening
Set a breakpoint in your code and debug your application step by step and you might find the reason of the error.
I'm using Vaadin 14 for an application that loads data from a database. I hava a AGrid object which loads data through a DataProvider and it uses a filter on the date.
When I set the filter in certain conditions I receive the error in the title but I cannot find no additional information about the origin of the error, Can someone please help me?
I tried changing Vaadin version, upgrading to the last v14 but with no success, I also tried to debug the application but I can't follow the flow to the origin of the error, it semmes to be fired by some Vaadin class
I am having a weird error when it comes to one of my projects in visual studio. I can start to debug, but when I run into an error or Visual Studio needs time to create a data tip my IIS express instance is lost and it will create a duplicate. After this happens and I try to hit the page again my browser will try to connect but will never get a response. I have tried to stop debugging and then start back up, but the IIS instance persists and I get the same result, trying to connect but no response. Also all of my break points turn to the not able to hit symbol.The only way to get back to being able to debug is to close visual studio and open it back up again. I'm sorry I don't have anymore information, but it almost seems to happen randomly.
Thanks in advance
Edit
This is what the break point looks like after I have stopped and restarted debugging.
I end up finding out the issue for anyone having the same problem. My initial question was not exactly what was happening. Whenever I stopped the IIS instance, the port that I was running the server on was being taken over by a Microsoft process. So when I hit run again my process was blocked and then showing the error above.
In order to fix this issue. I had to change the virtual directory for the project. You can do so by clicking in the web project and selecting properties. Pick Web on the left hand side and then change the url with to contain a different port and then click on create virtual directory.
I have what I perceive to be an unusual "syntax" error (at least to my very rookie junior dev self it is unusual)
I have a WP website that was originally built and designed by a friend, who wanted me to help. After logging on and attempting to upload a new theme to the website, legendsofthestands.com, I received the following error message:
Parse error: syntax error, unexpected end of file in
/home/kcsuperf/public_html/legendsofthestands.com/wp-content/themes/zerif-lite/functions.php
on line 1028
The problem isn't so much the error message, it is now that I'm not able to access the admin login page without seeing the same error. My understanding is that this is due to plugins that need to be deactivated so that I can access the /wp-admin page. However, when I try to access the admin console via FTP, I keep getting the 530 login failed error message.
I'm not sure which route to go at this point, whether I should try and contact the hosting company to resolve the logon issue, or if there is a way to fix the parse/syntax issue without having seen the code (since it is a WP-installed site).
Any assistance is appreciated.
I wasn't able to find anything helpful through google, so:
My Dart webapplication worked perfectly. Next time I opened Darteditor and (without changing anything) ran it again, Darteditor showed the Error
Breaking on exception: Strict get failed, invalid object.
This Error doesn't always show up and even when it does, the App still functions. Darteditor doesn't give me any hit where that Error occurs, because the debugger claims some source not to be available.
Does anyone know why/when this Error occurrs and what to do to fix it?
EDIT 1:
As suggested in comments:
updating Darteditor
pub cache repair
pub upgrade
Did not work
EDIT 2:
A Day after I tried the things mentioned in EDIT 1. Thus also after I rebooted the PC. At the moment, the Error doesn't appear anymore. I tried restarting the Darteditor after each try in EDIT 1 but nothing changed. Now...some of the things in EDIT 1 seem to have taken effect only after rebooting the PC. Not sure which of those though - am I supposed to answer my own question mentioning all 3 options from EDIT 1 or what should I do?
EDIT 3:
(Sorry for all the edits)
I changed some code now and the Error is back here again...
Sometimes it goes away, but not with a obvious reason like a specific line of code added/removed. Right now, ther is an additional line by the Error:
Application Cache NoUpdate event (https://www.google.ch/xjs/_/js/k=xjs.ntp.en_US.mqcA3JMW-QU.O/m=jsa,ntp,pcc,csi/rt=j/d=1/t=zcms/rs=AItRSTO3mHFV3hPPmf2KYlzqp_GC2s-5GQ:119)
Breaking on exception: Strict get failed, invalid object.
I get the same error message when I click the back button in Dartium,
or when I use the backspace key and the focus is not in an editable
field (which triggers the back button). I think it's either a bug in
Dart or Dartium. – Damien Aug 21 at 14:00
Interesting: When I pressed the back button in dartium, the error did
show up, but after this, it said something about application cache
(about 5 lines of text) and now I cannot reproduce the "strict get
failed" Error message – lucidbrot yesterday
pressing the back button in dartium, which I never did before, seemed to help in my case. Updating Darteditor again after this didn't change anything - the strict get error disappeared.
I won't accept this answer until somebody comments that it worked for him too, but I guess it is better to view here than as a comment to my question.
