Mentimeter for Powerpoint add-in error: This add-in could not be started... about office-js

[oleksiihopchenko]

Hello @EsterBergen! Thanks for the quick response. We do not support web version. So it's just win 32

[FilipStenbeck]

We have deployed a fix and we have seen that now that we return 200, the integration loads. Thank you for your help!

[EsterBergen]

@FilipStenbeck - so glad it works now! @croicu - thank you for tackling this customer issue!

[EsterBergen]

Thanks @oleksiihopchenko for sharing this! I can see it for Mentimeter on version 2404. Will look into this and will respond back here. Do you also see this on web, or just Win 32?

Hi @EsterBergen. Any insights on this issue? Our users are still experiencing it :(

[FilipStenbeck]

@EsterBergen Hi, has there been any progress with this issue?

The problem is the first page load returns HTTP error 500. This is treated by Office as an unrecoverable error and this is why we are displaying the error banner:

I believe that returning 200 will fix the error without the need for a client fix.

[EsterBergen]

@FilipStenbeck and @oleksiihopchenko - Can you try the proposed fix above and let us know if that resolves the issue?

[FilipStenbeck]

Thanks for reaching pout for us, we will investigate why we get a 500 error and see if there is a way to get around that error.
