Hi @pdsaz,

Did you run into the issue clicking "Create a flow" or "See your flows" from Sharepoint? 

If "Create a flow" could you please post the url of the flow you clicked on so that I can investigate?

Thanks!

Hi Travis - Thanks for helping.

while viewing the list in sharepoint i clicked on the "Flow" drop down then selected "Create a Flow" which opened a panel on the right.  I selected "Send approval email when a new item is added".  This took me to the Microsoft flow site with my sharepoint address filled in.  The list name showed as number not the list name with the error I posted.  I logged off and tried again with same result.

Hope that is some useful data.

Do I understand correctly that you're running into a different issue now?

The first issue was that the list name was correct, but you received an error stating "Value cannot be null.  Parameter name: accessToken"

The second issue is now that the list name is incorrect?

Or are they both the same issue? Sorry for the confusion!

[pdsaz]

both. happening....  Sorry if I confused the information.  I am new to flows...

Hi @pdsaz

No problem, I'm happy to help!

It looks like their is an issue with your connection. Could you try deleting and recreating your sharepoint connection and seeing if the problem persists?

Hi pdsaz,

May I know is this error appear after you paste an SP URL in actions? If so, make sure that your site URL is like "https://contoso.sharepoint.com/" instead of "https://contoso.sharepoint.com/SitePages/Home.aspx".

Hi @pdsaz,

Sorry for not updating you while we investigate the issue. It looks like you aren't the only one facing this problem.

Some additional information would be helpful in narrowing down your individual requests. If you press ctrl+alt+a on any page on flow (believe this only works in chrome), it will pop up some useful debugging information.

Could you email that info to the following address, citing this forum post:
flowdev@service.microsoft.com
