Describe the bug / error

We have an API query which gets a hero component from a specific SitePage under SharePoint.

Example:

https://graph.microsoft.com/v1.0/sites/$siteId/pages/$pageId/microsoft.graph.sitePage/webParts/$heroComponentId

When getting each tile within the hero, I am finding an inconsistent behaviour with the image data provided for each tile.

More recently, the hero component has background image settings of "Auto-selected image" and "Custom image". I am finding that in some cases when the "Auto-selected image" option is selected, the actual image being returned is what has been set on the Custom Image, even though this not currently set on the hero itself.

It doesn't always happen either, however to fix the issue I need to change the "Custom Image" set even though "Auto-selected image" is selected on the title.

This seems like an API behaviour, given we can't directly influence it via the hero web part settings.

Steps to reproduce

See description of bug/error, as it is more API related.

Expected behavior

The image set on the tile to be returned, rather than an image that exists but it is not set on the tile.

@jamesmacwhite,
I was able to reproduce the behavior described.
API response does not match the current tile setting, even though the UI shows Auto-selected image.

It seems this may be more of a Microsoft Graph API behavior issue than a sp-dev-docs problem. I’ll first confirm with the engineering team whether this should be reported as a valid bug.

Hi @Ashlesha-MSFT. Yes, that matches the scenario I see, the tile data seems to return the Custom Image when Auto-selected is actually in use, although it isn't always the case, so I'm not entirely sure on the specific case that triggers it.

That's correct, it is more likely a Graph API area, but I had no idea where to report it and had previously reported Microsoft Graph API areas here before that specifically used SharePoint API areas, so I hope that's OK.

@jamesmacwhite ,
Thanks for confirming the scenario. We were able to reproduce the behavior on our end as well.

As this appears to be an API-side issue, we will go ahead and raise a bug with the engineering team for further investigation and keep this thread updated once we have more information.
