A list inside a File.ext YAML key pattern is not correctly parsed

[kuisathaverat]

I found the following error message for a valid values YAML file

/folder/readme-generator-for-helm/lib/parser.js:147
        _.get(valuesJSON, arrayPrefix).forEach((e) => {
                                      ^

TypeError: Cannot read property 'forEach' of undefined

This is the yaml file, it contains a key with a . because it references a file.ext pattern, this key contains a list that is where the parse error happens.

## section foo bar
## @param foo.file.ext.foo bar
foo:
  file.ext:
    foo:
      - bar

Removing the file.ext key the parser pass.

In my case, I am creating a Helm Chart on top of the Grafana Helm Chart and defining a Grafana dashboardProviders

The main problem here is that it was not easy to find what caused the error.

Sorry for my very late response

I've just created an internal task to work on this issue. I hope to come back soon.
