Can't upload image over 110k

[ErixWong]

I running a redmine 4.2.5.stable in docker based on the docker official image. After installed redmine_ckeditor I found pictures over 110k can't be uploaded.

Error Message:
Completed 500 Internal Server Error in 29ms (ActiveRecord: 20.2ms)
TypeError (no implicit conversion of nil into String):
lib/redmine/sudo_mode.rb:61:in `sudo_mode'

Meanwhile I can upload attachments, I also set the limitation of file upload size, but it doesn't work to redmine_ckeditor

I also found small pictures will be uploaded to /tmp first, error ones will not appear in /tmp
I checked the /tmp, it's not full, big enough. I also can download big files manually by redmine:redmine in tmp.

Well, is there any place where this limit can be set? Thanks a lot.

same error here, with Redmine running in docker container when uploading image to ckeditor (POST method in Redmine logs).

We do not have this error when posting same files to tickets attachments.

Same problem. Is there some place I can config the upload image size limit?

Hi, in case anyone is still following this issue, I found the fix on a StackOverflow post :

https://stackoverflow.com/questions/76716910/cant-upload-image-on-redmine-5-using-ckeditor

Edit redmine_ckeditor/assets/javascripts/browser.js, line 318 :
from : handlerClass = 'UploadHandlerXhr';
to : handlerClass = 'UploadHandlerForm';

This fixed the bug for me, using Redmine 5.1.0 with CKEditor plugin fork from https://www.redmine-x.com/redminex-ck-editor-free
