Hi, what am I doing wrong here?

@WearPreviewSmallRound
    @Composable
    fun TilePreview(){
        Text(text = "Peek News")
    }

The error: This preview was unable to find a CompositionLocal. You might need to define it so it can render correctly.

[Zach Klippenstein (he/him) [MOD]]

Does the error or stacktrace indicate which compositino local is missing?

[Nat Strangerweather]

I'm not sure. Here is the StackTrace:

[Zach Klippenstein (he/him) [MOD]]

huh, that looks unrelated to me. Where are you seeing the missing composition local error?

[Nat Strangerweather]

When I click on the triangle with the exclamation mark here:

[Nat Strangerweather]

I see this

[Zach Klippenstein (he/him) [MOD]]

Definitely sounds like a studio bug, please file

[Nat Strangerweather]

And when I click on "Exception" I get that Stack Trace

[Nat Strangerweather]

OK

[Nat Strangerweather]

Thank you!

[florent]

I think that's an issue with glance. I am not quite sure it supports that kind of preview

[yschimke]

That preview of glance isn't supported.

[yschimke]

Also glance tiles was not included in the latest release. So you may hit issues when you update dependencies.

[yschimke]

Consider using the tiles material components. Nice utilities for previews in the Horologist library.

[Nat Strangerweather]

Shall I cancel my bug report?

[yschimke]

Yeah, I don't think it's meant to be supported
