"Message length exceeded maximum allowed length" on script update

[redweller]

Expected Behavior

Script is installed.

Actual Behavior

Infinite "Please wait" window.

People are having trouble installing a userscript on Chrome. This userscript gave no issues in the past, and it still can be successfully installed on Edge and FF.

When clicking the link to the script, TM opens the import tab and says "Please wait", then a file save dialogue pops. After that the Please wait message remains forever. This actually happens whenever the script is loaded - via link, via file, or if I manually copy paste it, change the version to a lower one and try updating. But if I copy-paste the script, it works. The other scripts I have tested are installed as usual.

UPDATE I've been assuming that this error happens on any install/update operation, but it turns out the fresh install is OK, but any subsequent updates except for the manual copy/pasting the code, result in the infinite "Please wait" window. Also it seems this has something to do with the size of the script being updated. Scripts >30Mb have this behavior.

Can not reproduce.

Please open the developer tools (ctrl+shift+j) and check the console tab for error messages.

Update: I've emptied my TM trash bin, and the script can be installed again. But any update operation leads to the same error, Below is the console output that happens when I just try to check for updates. In this case, it doesn't show the "download file" dialog, and the two subsequent console messages don't appear, just the "Please wait..." stuck forever

[redweller]

Some further research showed that the issue is indeed only related to script updates, and depends entirely on the current script, the one it's being updated to seems irrelevant. Also, as a hypothesis, this happens when the current script exceeds 30Mb size. I'm not absolutely sure, but it seems like it.

Also, Im sorry for the initial confusion. It's just the first person to report this said they were trying to "install" the script, so it didn't occur to me to explicitly check the fresh install.

No problem. I can reproduce it now...
