Thanks for the quick response.

I did question the strange imbalanced looking quotes, but apprently it is correct and has to do with handling of the variables/strings and so on within PS. And the --output was working with the same imbalanced looking quotes anyway.

But, your suggestion for checking file existence got me to the answer: Because I'm using absolute paths when calling generate.js, I need to also specify the file extension .json on the end. Not needed on the output side as I guess your js handles this. For completness I have added it on the output side anyway.

Thanks

Try to print the `$inputFileName` and check if the file actually exists.

The quotes seem to me unbalanced here:

 "--input", "`"$inputFileName`"",

Edit: The backticks are correct!

Hi All

I've recently got into EG and I'm trying to automate as much as possible. I started with DOS cmd, but I am now moving all my programs onto Powershell, so I can then move to Linux, so I can then get a Cloud VPS to run things 24/7. The Powershell on Linux part is to avoid expensive Windows cloud licences, but still remain compatible with my local machine.

Attached is a validate and generate powershell script. It runs, but it can't find any existing collection to load - and I know they exist. It ouputs the collection at the end of the run perfectly well. It can't then read it back in.

Any ideas? Maybe I've gone bug-blind and can't see something obvious in my code :-/

Many thanks.
