Unexpected token in key, error message being fuzzy

[AndersBillLinden]

When I use <div vc-recaptcha key="1234"></div> where 1234 actually is the code I got from https://www.google.com/recaptcha, (digits and letters without hyphens), I get the script error Syntax Error: Token '234' is an unexpected token at column 2 of the expression [1234] starting at [234] where 234 is the actual code, previously mentioned without the first character.

So it seems like my key was unparsable.

This issue could be a report of the kind unclear documentation or improvable error message. What is expected instead of the string I am using?

In your documentation the attribute key consists of both apostrophe and hyphen, but the documentation does not stress the presense of those characters. (I tried to include them without luck).

Ok, a key needs to be surrounded with apostrophe and no hyphens, could the documentation be updated with clarification about that, please?

I see in the documentation:

Here, the key attribute is passed to the directive's scope, so you can use either a property in your scope or just a hardcoded string

This is all pretty standard angular stuff. When you are passing a value to a directive binding, you write an angular expression in the attribute.

Is not that we require double quotes, we just require an angular expression.

Ok, I think I was just inexperienced, thanks then :)

Not sure why this issue is being closed. I have tried to add single quotes inside of double quotes and this still does not function correctly. I am not using a Angular expression but a attribute and string value. Still get a unexpected token at column 2 of express [key] starting at [key].
