Office365Groups.ListGroupMembers failed: The Method 'ListGroupMembers' has an invalid value for parameter 'groupid'

[johnjohn123]

I have the following formula to check if the login user is inside a group named "SRM Dev Admin User" and redirect the user to a specific start page:-

but the above formula is raising this error:-

Office365Groups.ListGroupMembers failed: The Method 'ListGroupMembers' has an invalid value for parameter 'groupid'

Any advice on this please?

Hi @johnjohn123 ,

I answered this earlier with a reference to my blog. Just get the Id of the group (as in first part of blog) and this works

If(
    User().FullName in Office365Groups.ListGroupMembers(
      "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
   ).value.displayName,
    AdminHomePage,
    VendorScoreCard_1
)

@johnjohn123 ,

I am struggling to understand why not when it is so simple, but expanding the logic (this structure is actually in my blog)

With(
   {
      wGroupID: 
      LookUp(
         Office365Groups.ListOwnedGroups().value,
         displayName = "Your Group Name"
      ).id
   },
   If(
      User().FullName in Office365Groups.ListGroupMembers(wGroupID).value.displayName,
      AdminHomePage,
      VendorScoreCard_1
   )
)

@johnjohn123 ,

I tested it here and got no errors, so not sure of the issue, however if it does not work (or the ID does not as well), then you may have to re-think your structure. I use a master SharePoint list of our employees (we have about 150 in the division) and have all their details in there. A lookup on that would certainly work.
