Why am I getting “Unexpected token string” error?

If you are getting “Unexpected token string..” error when adding query parameters or passing props in a widget in React instantSearch, you can check if your values contain spaces or apostrophes. 

If it contains spaces, you can enclose the whole value in single quotes. 

{ “filters”: “color:’Navy Blue’” } 

or

filters={“color:’Navy Blue’”}

If the value has an apostrophe(‘), you can put two backslashes in front of apostrophes and enclose the whole value in single quotes.

{ “filters”: “type:‘women\\’s’”} 

or

filters={“type:‘women\\’s’”}
