UserPhoto error

I am creating a power app which is forever coming up with the following error

Office365Users.UserPhoto failed: The function 'UserPhoto' has an invalid value for parameter 'userId' - a blank value was passed to it where it was not expected. Please make sure that a valid argument is passed to the function.

In the app I have a User Photo in the header for the current user, which is working fine. I also have a couple of entries in a gallery with User Photo's. Again both of these are working fine. When I have looked at past examples they imply that the ID's have no photo's assigned to them which is the cause of the issue, I have in this example, made sure the only ID's being used have a photo.

Try to use something like this, note that NoUser is a photo placeholder when no user is available

If( IfError( Office365Users.UserPhotoMetadata(ThisItem.BookedBy.Email).HasPhoto = true,"" ), IfError( Office365Users.UserPhoto(ThisItem.BookedBy.Email),"" ), NoUser )

since you have not provided your code, you will have to change it a bit

The email address of the corresponding user was not read by the App before it tried to obtain Office365Users.UserPhoto

Try below (it will change the sequence and your App will have User().Email before it sends a call to UserPhoto action:

If( !IsBlank(User().Email), Office365Users.UserPhoto(User().Email) )

Hi @happyume , @ahenn22
Thanks for the reply guys, I assume that I should copy this into the OnStart property of the app.

@nshaw75

if you do this, dont forget to manually run the onstart when testing.

I have added the text into the OnStart property and run OnStart. I don't have any errors in the formula in the studio but the error still appears whilst using it via Teams orr my phone. This is my code in he OnStart property

If(
!IsBlank(User().Email),
Office365Users.UserPhoto(User().Email)
);
Concurrent(
Set(varUser,User()),
Set(varUserEmail,User().Email),
Set(varUserImage,User().Image),
Set(varUserName,User().FullName)
)

Hi @mmbr1606

Yeah, I get into the habit of publishing instead of saving when I am in a test scenario like this one. As I can check the UX in reality

I have just noticed that now the error no longer appears on the Home Screen, however, the error is still showing when I navigate to the gallery screen, when in the gallery I have an image of the user which is an entry in a column in the sharepoint list. Each of the users in the list have a photo attached to their ID. The code I have for the images is Office365Users.UserPhoto(ThisItem.SamplePerson.Email)

Thanks everybody for the help. i have got the error to disappear definitely not as straightforward as I thought it would be. The formula I used eventually was
If(IsBlank(ThisItem.SamplePerson.Email), Icon.Person, If(!IsBlank(ThisItem.SamplePerson.Email), Office365Users.UserPhoto(ThisItem.SamplePerson.Email)))
