TypeError: Cannot read properties of null (reading 'render') about rollup

I'm working on a PR, will be finished soon

I get a similar error when running a build with Vite 5.2.10 that uses rollup 4.16.1:

The problem seems to be in LogicalExpression.render method here:

this.getUsedBranch().render(code, options, { // <--------
                isCalleeOfRenderedParent,
                preventASI,
                renderedParentType: renderedParentType || this.parent.type,
                renderedSurroundingElement: renderedSurroundingElement || this.parent.type
            });

Could you please suggest if this something not covered yet in rollup, or a misconfiguration on my side?

It is most probably a rollup error, I will check it later.

@liuly0322 not a minimal example project, unfortunately, but I'm able to reproduce with the example project that is attached to this issue- "k8s-demo-app.zip".

Download the project and run ./mvnw -B. Then the above error should show up in the console logs when Vite starts to build the bundle.

Yes, it is a rollup bug, thanks for spotting. It's weird that I don't know how to solve it now and will have a detailed look later.

It seems that there should be a new include call to this node after deoptimizeCache but there isn't.
