All backends failing with due to exception in doLittle.Assemblies.ICanProvideAssemblies

All backends running in our dev cluster are currently failing with the following exception:

Interesting. I notice that it is looking for a Web.PrecompiledViewsassembly. Are we doing something on build for precompiling razor pages? That sounds wrong if so - don't think we're supposed to be doing MVC + Razor Views.

Tips on reproduction locally?

[karolikl]

You should be able to reproduce locally if you pull and run one of the following images: karolikl/cbs-vr-backend:1488 karolikl/cbs-admin-backend:1489 karolikl/cbs-usermgmt-backend:1490

Building and running the backends locally (not in a container) works fine though.

We should definitely not use MVC + Razor. I've search the entire repo for "Razor", "ViewCompilation" and "PrecompiledViews" without any results.

My hopeful fix did not fix it. I think I have a way of reproducing it locally now - was going to deploy SmsEagle endpoint and got the same error.

[karolikl]

Changes are currently not being deployed to the dev environment automatically (as we're in the process of moving away from vsts). So the changes haven't been deployed yet. I can trigger a deployment now to see if it helps.

[karolikl]

Update: Will have to update the pods later on today. Will post a comment here when done.

[karolikl]

@einari, we pushed a new version last night, but the backends are still failing with the same errors.

[einari]

Yup. Was expecting that to fail. Didn't have time yesterday to fix it - hoping later today / tonight. I have the fix in my head - just needs to be done and tested.

[einari]

Fascinating... Different error - in fact, no error - no nothing. It just doesn't start properly. Investigating.

[einari]

Located and completely makes sense.. My bad; with the new inter bounded context communication system, it tries to hook up for a topic that it is expecting from an environment variable passed into the container.

Well.. I have that - but since it is not something that is set as a requirement, it is not included in the deployment. Weird enough though, it works in development but inside a container it just dies without any message. Found, reproduced, fixed.. PR coming.

We look forward to the PR 😊

Deployed, and it works!! 🥇
