Tried to upgrade to to 4.5.3 from 4.4.3 (I also tried 4.5.0) and I am getting an error in the dev tools console, just a blank screen when I try to hit the /admin page.
Uncaught (in promise) Invariant Violation: ‘maxLengthCharacters’ must be prefixed with ‘options.’
Downgrading back to 4.4.3 fixes the issue, just wondering if anyone has any insight on it. Thanks.
Hi. I just gave it another go, removing the .cache file, I did not do that last time. I removed the lock file, /.cache, /node_modules, and /build this time, then build and develop. I still get the same error.
There isn’t anything specific in this migration guide, the only version I skipped was 4.4.5, I checked that guide and renaming the favicon was the only step I had to do from there.
The full dev tools output is this:
Uncaught (in promise) Invariant Violation: 'maxLengthCharacters' must be prefixed with 'options.'

I spent a little time after my last post this morning and was able to get everything working. What I had to do was find the location of the “maxLengthCharacters” entry in main.a627abc1.js build file and re-save it with the edit “options.maxLengthCharacters”, now it works fine.
So, I’d say there is a problem somewhere in the build step.
I will give it a go on my remote server, if I have to edit the build fine there as well, I can do that but it makes me a little nervous for future upgrades if I have to keep in mind specific edit(s) to built js files.
I uploaded my schema changes to the remote production server just a bit ago with the latest 4.5.3 set for install. I npm installed then built the admin panel. I ran into the same issue.
So, basically I got into the specific main.xxxxxx.js file where the maxLengthCharacters string is located, did a quick find and appended it to read as options.maxLengthCharacters, this fixes the problem there as well.
Hopefully I won’t have to do this with each new build in future upgrades but it’s not a HUGE problem as it’s not really difficult to do.
It appears that this issue is realated to the ck5 editor plugin, which I added at the same time I upgraded. This property appears in the @ckeditor/strapi-plugin-ckeditor/admin-src/index.js file.
I opened up a new issue in their Github for this problem.
