✅ Malformed input: 321 is an invalid input length

I'm working with Asp.Net Core Identity. I use

GeneratePasswordResetTokenAsync(user)

GeneratePasswordResetTokenAsync(user)

to generate token and encode it with

WebEncoders.Base64UrlEncode(Encoding.UTF8.GetBytes(token));

WebEncoders.Base64UrlEncode(Encoding.UTF8.GetBytes(token));

. Next I decode encoded token with

Encoding.UTF8.GetString(WebEncoders.Base64UrlDecode(encodedToken))

Encoding.UTF8.GetString(WebEncoders.Base64UrlDecode(encodedToken))

and get exception:

An unhandled exception occurred while processing the request.
FormatException: Malformed input: 321 is an invalid input length.
Microsoft.AspNetCore.WebUtilities.WebEncoders.GetNumBase64PaddingCharsToAddForDecode(int inputLength)

An unhandled exception occurred while processing the request.
FormatException: Malformed input: 321 is an invalid input length.
Microsoft.AspNetCore.WebUtilities.WebEncoders.GetNumBase64PaddingCharsToAddForDecode(int inputLength)

How can I fix my problem?
