Describe the bug you're encountering

Start the swagger-ui docker container for 5.18.0 with default settings does not work and immediately quits with an error.

To reproduce...

Steps to reproduce the behavior:

1. Run docker run --rm -ti swaggerapi/swagger-ui:v5.18.0
2. See error message:

$ docker run --rm -ti swaggerapi/swagger-ui:v5.18.0

Expected behavior

I expect the docker image to work in its default configuration.

Screenshots

Previous versions work correctly:

According to the documentation, running it in a container like this without further configuration is supposed to work: https://swagger.io/docs/open-source-tools/swagger-ui/usage/installation/

Could this be related: #10192

Just made the same report, also pointing to that commit.
Note that also latest image is affected.

Seems like a breaking change to me.

[airtonzanon]

Having the same issue, any best practices to how to deal with it or it's a mistake?

Yes, that is for sure the cause. Removing node basically breaks usage of swagger-ui in containers.

Same problem here, hope it gets fixed soon

Hi everybody,

My fault. I've tested locally and I could execute node even without the explicit install. Obviously I did something wrong. Fix release is comming.
