How to solve terraform error for configuring local aws credentials?

I am using below code to for configuring aws creds.

provider "aws"  {
    region  = var.region_name
    profile = "default"
}

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 3.76"
    }
  }

  required_version = ">= 0.14.9"
}

I was getting below error whenever we run terraform plan

Error:

Error: error configuring Terraform AWS Provider: no valid credential sources for Terraform AWS Provider found.
│

│ for more information about providing credentials.

Solution

I tried upgrading my aws provider version as per https://registry.terraform.io/providers/hashicorp/aws/latest/docs/guides/version-4-upgrade#changes-to-authentication and it started working as below:

provider "aws"  {
    region  = var.region_name
    profile = "default"
}

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 4.0"
    }
  }

  required_version = ">= 0.14.9"
}
