How to resolve Invalid_grant error in Sitecore CLI

One on my forks encountered this error while using Sitecore CLI and its very common for Sitecore CLI users and that is invalid_grant error.

To resolve this error we need to put latest values of access token and refresh token in USER.json

so we have two ways to do this.

1. use this command and allow this on browser.

dotnet sitecore login --authority https://<sitecore-identity-server> --cm https://<sitecore-instance> --allow-write true

this we put latest values of access token and refresh token in user.json

2.By using postman post call we can get access token and refresh token values and put it in our user.json

Download postman and hit your identity server url with /connect/token 

in body send additional key values as sent in the above picture.

For first time users it will throw SSL certificate error for this just disable SSL verification

and hit post call again it will give you access token and refresh token. put the below values in body

x-www-form-urlencoded 

key       -       value

grant_type      -      password

client_id    -    SitecorePassword

username     -     sitecore\admin

password       -      b

client_secret      -        IdentityServerClientSecret

or you can directly import the below collection and change your identity server url.
