Invalid URI: The format of the URI could not be determined.- nopCommerce 4.10

Guys,

i have downloaded nopCommerce 4.10 Source Code and was able to run the application for the first time (configured admin user and database).

The next time when i try to run the nopCommerce 4.10 application it throws

'Invalid URI: The format of the URI could not be determined.'

This error is coming from ModifyQueryString method in nopCommerce_4.10_Source\Libraries\Nop.Core\WebHelper.cs.

        public virtual string ModifyQueryString(string url, string key, params string[] values)
        {
            if (string.IsNullOrEmpty(url))
                return string.Empty;

            if (string.IsNullOrEmpty(key))
                return url;

            //get current query parameters
            var uri = new Uri(url);
            var queryParameters = QueryHelpers.ParseQuery(uri.Query);

            //and add passed one
            queryParameters[key] = new StringValues(values);
            var queryBuilder = new QueryBuilder(queryParameters
                .ToDictionary(parameter => parameter.Key, parameter => parameter.Value.ToString()));

            //create new URL with passed query parameters
            url = $"{uri.GetLeftPart(UriPartial.Path)}{queryBuilder.ToQueryString()}{uri.Fragment}";

            return url;
        }

i have also underlined the code in the ModifyQueryString method where i am getting this error.

when ModifyQueryString method is called the url parameter of this method has '/changecurrency/1', key parameter of this method has 'returnurl=%2F' and the values parameter of this method has null.

i also checked this ModifyQueryString method in previous version (nopCommerce 4.0). their this method is having different implementation and parameters.

any suggestion for fixing this error would greatly helpful

Thanks.

I am also facing the same problem after upgrading. Any ideas?

Thanks. Here is a work item for it

What version of nopcommerce are you currently running and did you donwload the official release of that version or download it through a development version of the source code?

Also, can you please clarify that to recreate the issue you are saying that:

1. You downloaded an additional theme.
2. Changed the theme through administration.
3. Tried to log back in and experienced the exception.

Thanks

Also [email protected], if you can access your log in Admin -> System -> Log, has anything been logged regarding this issue?  If so please provide the Full Message.

Thanks

Hi, the error is in [Views\Shared\Components\OrderSummary\Default.cshtml] where

var editCartItemUrl = Url.RouteUrl("Product", new { SeName = item.ProductSeName });

should be replaced by :

var editCartItemUrl = Url.RouteUrl("Product", new { SeName = item.ProductSeName }, webHelper.CurrentRequestProtocol);
