Thanks, I'll make sure one of our functions engineers will take a look at this.

Hello there 👋
Thanks for raising the issue. I can see how this can affect developer experience, but I would like to raise a concern regarding some use cases.

For example there can be function to exportDatabase which would export all documents to CSV file. This function could accept required env variable CSV_SEPARATOR which could be (space), , or .. All I believe are reasonable separators.

With that in mind, space could be considered valid value for required parameter.

@Meldiron Thanks for highlighting the CSV_SEPARATOR scenario.
I agree that spaces can be valid in certain contexts, they can also introduce ambiguity in others like URLs, API KEYS, File Paths etc.

Suggestions:

1. Maybe disallow spaces as valid inputs across the function variables' input to prevent unintentional mistakes.
   For fields like CSV_SEPARATOR, allow only specific characters like . and , as valid inputs.
2. Far fetched, display a hint confirming if the User did use a space manually.
