错误：无法假定角色“ arn：aws：iam :: << my_AWS_account_number >>：role / sudip_terraform_ec2_role”

如何解决错误：无法假定角色“ arn：aws：iam :: << my_AWS_account_number >>：role / sudip_terraform_ec2_role”

//我在客户端环境中遇到的错误

    Error: error configuring terraform AWS Provider: IAM Role (arn:aws:iam::<<my_AWS_account_number>>:role/sudip_terraform_ec2_role) cannot be assumed.

There are a number of possible causes of this - the most common are:
  * The credentials used in order to assume the role are invalid
  * The credentials do not have appropriate permission to assume the role
  * The role ARN is not valid

Error: NoCredentialProviders: no valid providers in chain. Deprecated.
        For verbose messaging see aws.Config.CredentialsChainVerboseErrors
    
// "terraform init" and "terraform validate" works fine. After that,"terraform plan" gives the above error
