Microsoft 365 and Office | Publisher | Other
A desktop publishing application from Microsoft that focuses on page layout and graphic design.
I am having this exact same problem, and I, too, am exasperated by this!
Publisher giving Error 400 code?
![](data:image/svg+xml, %3Csvg xmlns='http://www.w3.org/2000/svg' height='64' class='font-weight-bold' style='font: 600 30.11764705882353px "SegoeUI", Arial' width='64'%3E%3Ccircle fill='hsl(128, 8%, 22%)' cx='32' cy='32' r='32' /%3E%3Ctext x='50%25' y='55%25' dominant-baseline='middle' text-anchor='middle' fill='%23FFF' %3EA%3C/text%3E%3C/svg%3E)

When I try to hit the pictures icon on publisher in the "Home" header to add a picture to something the window comes up saying:
"Bad Request- Request too Long. Http Error 400. the size of the request headers is too long."
If I go to insert at the top of the page and click picture there it will work for uploading pictures from my computer.
I made sure office is updated but not sure how to fix this.
Help please?

2024-03-26T21:50:20+00:00 I know that this doesnt fix the issue, but if I drug and dropped the photo into Microsoft Publisher (rather than adding the photo through the program) then the error didn't occur. Not really a solution, but a alright work-around!
Thanks Justyn, that worked. I've updated Office and run a quick repair but neither worked this week (did work last week)

1, Hit windows key and R at the same time for the "run" box to pop up.
- copy and paste the following to the run box %LOCALAPPDATA%\Microsoft\Office\16.0\Wef
(or browse to c:\users\YOURUSERNAME\appdata\local\microsoft\office\16.0\WEF)
- Delete the webview2 folder
This will clear the cache for the embedded webbrowser that office talks to the web with.
It worked for a similar issue for me today. I used process monitor to figure out that office was calling the microsoft webview2 control and the location of the user-data folder.
