ERROR: Failed to retrieve headers. about mha HOT 16 CLOSED

Could you open the gear icon and click diagnostics, then paste the output here?
My working theory here is that REST or EWS (likely REST) isn't working in your environment.

from mha.

Hi,

Thank you for replying. I apologize about post #18. Everything was working before and no major updates have been applied to our environment. How can I diagnose the REST or EWS?

Outlook for Mac uses EWS and everything seems to be working.

Let me know if you need anything else. Once again, thank you for looking into this.

I think I need to put some more breadcrumbs in my error code. But ultimately, I think this is gonna be a server issue. Fiddler will show the traffic of requests. As I note in #18 (comment), you should see one of them failing.

from mha.

Hi Stephen,
I am scratching my head on this one. I can't figure it out. I need additional guidance. I have installed other apps and these work without no issues.
Using IE (F12) and Fiddler. I see the traffic to this website https://mha.azurewebsites.net/ and not https://outlook.office365.com.

from mha.

I’m on vacation for a week, but when I get back I’d love to look at the fiddler output.

from mha.

Updated error logging should get us an error message+stack now

from mha.

I've also been getting this -- immediate error is "Failed to Retrieve Headers"

On the hunch that namespaces are an issue, I renamed my callback - if this fixes this issue I need to do real work to clean up namespaces.

Hi Stephen,
Thank you for checking this. The new diagnostic displays the same error as Skipdog77.
Not sure what is causing the error. Last week, I used Fiddler and IE dev tools and noticed some weird messages right after I click the MHA button. I hope these help, let me know if I can do something to help more.

**** The results below were obtained using Fiddler and the IE developer tools **
<EDIT: @stephenegriffin removed a list of string constants not relevant to this issue>

from mha.

Dunno if I've fixed this one, but I think the error should change. Please speak up if you're still getting "Sys.ArgumentNullException: Value cannot be null. Parameter name: callback" or if the error has morphed. Also let me know if that was your error and now it works. Thanks!

from mha.

I've got a repro of this now...

from mha.

Ok - so here's the bug:
Outlook 2016 MSI uses an older version of outlook-win32-16.00.js than Outlook 2016 C2R. In the older version of this file, there is some code to check that a callback function is indeed a function. This code looks like this:

            if(Function.isInstanceOfType(args[0]))
                callback = args[0];

However, this returns false for our callback function. Over in C2R, this same check now looks like this:

            if($h.CommonParameters._argIsFunction$p(args[0]))
                callback = args[0];

Where argIsFunction is defined like so:

    $h.CommonParameters._argIsFunction$p = function(arg)
    {
        return typeof arg === "function"
    };

So in 2016 MSI, makeEwsRequestAsync thinks we didn't pass a callback, but in 2016 C2R, it correctly concludes we did.

Action plan: Report this back to Office dev, and also continue to hack to see if I can force something past the isInstanceOfType check.

from mha.

Didn't mean to close this without verification - anyone still getting Failed to retrieve headers? If you were getting it and it's now fixed, please report that. If you're still getting it, please report updated diagnostics output, including the stack. Thanks!

from mha.

Hi Stephen,
Sorry, still partially broken. Here is my feedback. Thank you for working on this.

Outlook for Windows

• Both Classic and New work great.

Still broken on these browsers and clients. Neither Classic or New view worked:

• IE Firefox and Google Chrome Mac and Windows.
• Broken for Outlook for Mac

@luisjmoreno It looks like neither of those errors/stacks match the "Failed to retrieve headers" issue, so I'm gonna declare this one as fixed. I'll open new bugs to track these issues.

from mha.

This was caused by issuing our requests from an iFrame. Fixed by #50 which moved the calls back to the main frame
