Sharepoint On-premise App-Only Authentication fails.

[janandreschweiger]

Hey everyone, I have created a local sharepoint on my computer and would like to use your package. Unfortunately the authentication fails with the following error. Others have mentioned an IndexError for user-authentication, but this error occurs when using app-only authentication and has a totally different traceback.

My sharepoint isn't connected to Azure, thus I use the local ip of my sharepoint-vm as site_url. I have successfully created and granted access as described here .

My team and I really appreciate any help.

Error:

IndexError                                Traceback (most recent call last)

My firm faces the exact same issue. Could you maybe have a look on this one @vgrem? We are really desperate for some help.

Same here. Thanks @vgrem for having a look.

Isn't site_url supposed to be of the form https://abcd.sharepoint.com ?

Hi did you find a solution for this? My sharepoint on premise also doesn't have "sharepoint" in its site_url and I'm receiving IndexError: list index out of range as well . Is there a way to bypass it?

Hi Is someone found a solution ? workaround ? Facing same issue with on premise instance I have seen that using Client_id/Client_secret could work instead of using user/password. My problem is that I don't have the permissions to create client_id/secret and it could be complex to obtain so I would to know if it is a real solution or not before "moving mountains"
