Running Elsa Studio wrappers in a Blazor Web App with Interactive Server rendering

[Nekrosis1]

TL;DR: My Activity boxes are invisible when using Interactive Server side rendering to display Elsa components. How do I fix this?

We are currently planning to transport our Blazor WASM app to a Blazor Web App.
We use the wrappers for Editor and Instance, to integrate these GUI into our app.
I created a new, empty Web App and attempted to get Elsa Core and Elsa Studio to run, this worked quite well.
However, under certain conditions, the performance of these components is rather slow, but having them rendered server side remedies this quite well.
Unfortunately, when using Interactive Server side rendering for these Elsa components, the Activity boxes are invisible. Everything else works, even the Activities themselves are functional. Ports and connections do show up. I get no errors. This only happens when I use Server Side rendering. Using Elsa Shell with server side rendering does not produce this problem, the activity boxes show up.
I searched far and wide for a misconfiguration or something missing, but I cannot find anything.
Has anyone had a similar problem or know how to solve this?

Hi @Nekrosis1 , do you have a simple project perhaps to reproduce the issue?

Hi @Nekrosis1 , I received a notification of your reply, but I have not yet had time to look into it. Once I do I will report back here. Thank you.

One thing you might want to take a look at in the meantime is this reference application: https://github.com/elsa-workflows/elsa-apps/tree/main/src/Elsa.Server.Studio.BlazorServer

There, the activities show up correctly. The application is an ASP.NET Core + Blazor Server app that references the Elsa Studio packages. I.e., probably a similar setup to what you are using. Perhaps you see any important differences?

I tried to build my project according to the projects in Hosts
https://github.com/elsa-workflows/elsa-studio/tree/main/src/hosts
and the project in Server apps
https://github.com/elsa-workflows/elsa-core/tree/main/src/apps/Elsa.Server.Web
I tried to do everything like in those Projects.

I had a look in Elsa-Apps. If I am not mistaken, those are the same projects that are in studio/host and elsa/apps. I could not find any difference that would explain my issue.

Maybe try looking at the de develop\3.6.0 branch first, which is more actively being developed than main.

Sorry, bad links. I did use the develop 3.6.0 as reference, since I am also using packages on the version develop 3.6.0
