Previews not working after updating to 1.8.3

[OwainJ]

Which Umbraco version are you using? For example: 10.4.0 - don't just write v10

13.2.2

Bug summary

After updating from 1.8.2 to 1.8.3, the block list previews have stopped working.

Downgrading back to 1.8.2 fixes the issue, and the previews render as expected.

There are no errors in the browser console, or the Umbraco log, but I can see that the preview markup API response is empty:

Whereas on 1.8.2, the response looks like this:

Steps to reproduce

• Update from 1.8.2 to 1.8.3

I haven't tried reproducing this on a fresh install yet, will update when I do.

Expected result / actual result

Previews should render.

@OwainJ I think it might be same issue / or related, as this one: https://github.com/rickbutterfield/Umbraco.Community.BlockPreview/issues/50 can you try to move them to blockgrid folder just to see if is the same?

[OwainJ]

Hi @bielu, yup, can confirm that moving my /Components folder from /blocklist to /blockgrid got the rendering working:

1	2

Note: my block list is not nested like in #50, it's just a property on a DocType

interesting!

I'm having the same problem with Umbraco.Cms 13.3.0, Umbraco.Community.BlockPreview both with 1.8.2 and 1.8.3.

Works perfectly with Umbraco.Cms 13.2.2 and BlockPreview 1.8.2

Hi @OwainJ, @AlexanderWagner82

There's a fix for this (of course it one only a one liner!!) that's being released as v1.8.4 right now. Please give it a try once released to NuGet and let me know how you get on.

[OwainJ]

Happy to confirm that it works perfectly for me now on v1.8.4! Cheers Rick!

Works like a charm on Umbraco.Cms 13.3.0. Thank you very much!
