[HolQue]

"" : 1

causes:

'Invalid key name: "". Key names have to start with a letter, digit or underscore.'

This does not really makes sense. Please change to:

Empty key name detected. Please enter a valid name.

[HolQue]

Same with

" " : 1

As per

#356 (comment)

leading and trailing blanks shall be removed from key names. Finally the key name is empty therefore.

Also this case should cause:

Empty key name detected. Please enter a valid name.
