“Error code 195: Missing or invalid url parameter” when using tweets.json

restapi

#1

I keep getting the above error (HTTP status code 403, Error code 195: Missing or invalid url parameter) when using the search API for a specific query parameter value.
https://api.twitter.com/1.1/search/tweets.json?q=from%3AGeogDWI_HGS%20since%3A2017-02-01&result_type=recent&count=1&include_entities=true

I am using LinqToTwitter to make the api call to get tweets from user “GeogDWI_HGS” and below is the query string generated by the library.
from%3AGeogDWI_HGS%20since%3A2017-02-01&result_type=recent&count=1&include_entities=true

Can you check what is wrong with api request?
