Throw error if file not found.

[ivanjeremic]

From the examples I cannot find anything on how to error out if an file does not exist, any info on how I would do that? Thanks

I have the exact file name in my filter in the endsWith(...), this is my filter.

 walk(".", {
    deepFilter: (entry) =>
      !entry.name.startsWith(".") && !entry.name.startsWith("node_modules"),
    entryFilter: (entry) =>
      !entry.name.startsWith(".") &&
      !entry.name.startsWith("node_modules") &&
      entry.name.endsWith(`${el.tagName.toLocaleLowerCase()}.html`),
  });

walk is part of a function from which it gets the el.tagName, what I want is if
el.tagName.toLocaleLowerCase()}.html does not exist, stop and throw error, is that possible? For this the walk function must somehow know that it goes over the files the second time and there is still no file with that name so throw an error.
