Strange issue with invalid_grant error

[dguard]

Hey !
Thanks for your development. It is very useful !

Previously it worked for me but now I getting this error
{ error: "invalid_grant", error_description: "Code is invalid or expired." }

If I paste code manually from UserStore into this link below then it works, but that not works through backend (unprocessable entity)

https://oauth.vk.com/access_token?client_id=${CLIENT_ID}&client_secret=${CLIENT_SECRET}&redirect_uri=http://localhost:3003/signin&code=${CODE}

What's wrong? It works only within first seconds and then disappears

Best regards,
Alex
