onloadwff.js Assertion failed: Input argument is not an HTML

Please see this line of code:

return console.assert(t instanceof HTMLInputElement, "Input argument is not an HTMLInputElement")


When there's a form with textarea, and textarea changes(e.g. type enter in textarea), this error appears.

Bad news: This problem was posted several times in the forum now and is over one year old, nothing happened so far and I think there will no be a fix. Only option is to look for another password manager as we're going to do.

Re: onloadwff.js Assertion failed: Input argument is not an

+1 I'm seeing onloadwff.js errors while developing web pages. Is there a way of disabling LastPass within HTML to stop Javascript console errors while I'm working on regular pages?

+1 this is causing our error monitoring code to fire and add noise into our monitoring so it distracts us from real problems, would be great to have a fix

Hello,

I also want to report that this error is logged when a <button> is present in a form. This is a valid form input, and in HTML5 it's actually recommended to use in place of <input type="button">.
