If you are getting “filters: Not allowed incomplete string...” error when adding query parameters, you should check whether your values contain spaces, apostrophes or double quotes.
If the value contains a space, you can enclose the whole value in single quotes.
{ “filters”: “color:’Navy Blue’” }
If the value contains an apostrophe (‘), you can put two backslashes in front of apostrophes and enclose the whole value in single quotes.
{ “filters”: “type:‘women\\’s’”}
If the value contains a double quote ("), you can place a single backslash before the double quote and wrap the entire value in single quotes.
{"filters"= "length:'14\"'"}
