There was missing quote. Usually it is correct info from error
and it can tell also what character.
I'm not a professional programmer, but I think that,
Bash only checks the number of quotes ( for bash )
 and ignore commands with regular expressions.
( maybe grep, sed , awk )
This is a very quick method to check, but it can not accurately check.
And that is the reason
 why it does not know where to look.
The rules of programming are very determined, so exist ways to debug.
I do not ask you to fix this, because build debugger it is not easy.
This is the reason why I wrote only "add suggestion".

I do not know, You can write on the blog or other website ...
And people will write all the terms.
( for sed , awk , grep and other command when single quotes can be ignored )
In future this terms can be used for debug,
first in $() , later everything outside.

Not, because for missing "fi"  is other error and also 
this is not very accurate, but it can point to a broken function.
Poor comfort, but better than nothing.
