Trouble with JS API v3.4 in IE8

Question

I have a JS API v3.4 web application that works fine in Chrome, Firefox, and IE 10, but for some reason in IE 8 the page won't load.

When I look at the console in IE 8 all I get is:'undefined' is null or not an object

This error says it occurs in the 3.4 API file at line 15, character 13,092, which doesn't help me at all in determining the cause of the problem because the API is minified.

Any idea what could be causing this issue in IE 8 only?  According to the JS API docs, it should be supported in IE 7-10.

If you can post all your code we can take a look.

Well I tried JSHint and found a few issues.  They're all fixed now, but still having the same issues.  It looks like the issue occurs at require(["pgonline/Main"]...

It doesn't even get to var settings...

If I put a breakpoint in the constructor of Main, the breakpoint will not get hit.  A breakpoint isn't even hit if it is at return declare("pgonline/Main"...

inside the Main module.

I have no clue what could be happening.

Thanks for all the help.

IE can be picky about things that other browsers (Chrome, Firefox) are ok with like undeclared variables, trailing commas and missing semi-colons. Try running the code in your main javascript file through a problem detection tool like js hint and see if it returns any issues:
