[knowacki23]

Plugin Name

jenkins

📜 Description

When using Jenkins plugin with Multibranch Pipeline that haven't been built yet plugin displays a TypeError with following message: D.lastBuild is null This is how the affected Jenkins Pipeline looks like:

Following error at Entity Overview Page where we are using EntityLatestJenkinsRunCard:

👍 Expected behavior

It should display an information that no builds have been found instead of an error which looks like there was some problem with the plugin or connection with Jenkins instance.

On the other hand for one of the sub-pages for the same component we are using EntityJenkinsContent which displays information this way:

Something similar to the screenshot above would be nice.

👎 Actual Behavior with Screenshots

It actually displays following error at Entity Overview Page where we are using EntityLatestJenkinsRunCard:

👟 Reproduction steps

1. Add a EntityLatestJenkinsRunCard to overviewPage.
2. Register an Entity with a jenkins annotation pointing to a Multibranch Pipeline which haven't been built yet.
3. Check the Entity overview page.

📃 Provide the context for the Bug.
