Clojurians Log v2

Hi, I am trying to use lookahead

(re-find #"(?![\"]).*(?=[\"])" "\"a\"")
=> "a"

But when I use the same rule in Instaparser I get an error. Can you help me here please?

(instaparser "\"a\"")
Parse error at line 1, column 1:
"a"
^
Expected one of:
#"(?![\"]).*(?=[\"])"

Edit: but this works <'\"'> #'([a-zA-Z0-9_\\s]*)' <'\"'> Edit2: I solved it via string = <'\"'> #'[\\s\\S]'* <'\"'> and then i am joining all characters in transformation.
