We have two forms in particular that have been running without issue for more than a year, and with no changes made to the forms, the server, nor the Machform instance, users started experiencing a blank confirmation page after submission, and the only thing in the Chrome browser's console is:
Failed to load resource: the server responded with a status of 500 ()
crbug/1173575, non-JS module files deprecated.
(anonymous) @ VM9:1955
We get the same error in both current versions of Chrome and Microsoft Edge.
Firefox crashes with:
POST https://forms.benicomp.com/confirm.php [HTTP/2 500 Internal Server Error 955ms]
This page is in Quirks Mode. Page layout may be impacted. For Standards Mode use “<!DOCTYPE html>”. confirm.php
Last night we patched linux, apache, and all related packages and upgraded Machform to 18.1, and we are still getting this error.
The crbug/1173575 issue is related to -> https://bugs.chromium.org/p/chromium/issues/detail?id=1173575 which mostly discusses "Appcache internals: Migrate to JS modules" and related deprecated JS files.
Any insight into this issue would be greatly appreciated.
