"Not inside a Renderpass" error when calling camera.Render() in URP?

[celest pilot]

Not sure if this is better here or in #1390346776804069396 , but in URP I am calling camera.Render() in the editor to create previews/thumbnails for assets. But for some people's projects in Unity 6 they get these errors:

extSubPass: Not inside a Renderpass
UnityEngine.Camera:Render ()
etc....

EndRenderPass: Not inside a Renderpass
UnityEngine.Camera:Render ()
etc....

BlitFinalToBackBuffer/Final Depth Copy: Missing resolve surface for attachment 0. Are you tring to resolve a bindMS rendertarget?
UnityEngine.Camera:Render ()
etc....

Any ideas what it could be? I can't repro it myself. But is happening for a number of people.

This might imply that the timing you call it is bad. Likely in the middle of unity recording commands for it's render passes.
Is it in update?

It would be in EditorApplication.update

I don't know if it's the correct place to call camera render.
One thing you can try is disabling graphics jobs in the project settings and see if you can reproduce the error.
