getAccessTokenAsync give me 5001 error

[dianibar]

Hi,
I follow all the steps given in the example and then when I try to run the add-in in power-point on-line Build:16.0.8812.5630. I got the next error:

Code:5001
Message: An internal error has occurred
name: Internal Error

Any ideas what this is happening? Can I use the SSO in this build version?

Thanks for your help.

Please install the Fiddler tool (or Charles tool) and see what the network call looks like when getAccessTokenAsync runs. There are links to the tools in this article: Troubleshoot SSO in Office Add-ins
