User can`t enter 2 negative values to "Climate at origin" filters.
Steps to reproduce:
- Go to "https://sandbox.genesys-pgr.org/a".
- Try to enter to any "Climate at origin" filter 2 negative values (e.x "-15" and "-3").
- Click "Apply filters" button.
Expected result: The user should be able to enter 2 negative values.
Actual result: The second entered value is replaced to "NaN", after applying filters error message "Request failed with status code 400 JSON parse error" is shown. And the text of the error doesn`t fit into the frame of the browser window.
