Can someone please help on the below error:

Error: Failed to install provider

My providers.tf file looks like below :

terraform {
  required_providers {

    bitbucketserver = {
      source  = "gavinbunney/bitbucketserver"
      version = "~> 1.5"
    }
    kubectl = {
      source  = "gavinbunney/kubectl"
      version = "~> 1.14.0"
    }
  }
}

I am trying to install the latest version of the providers.
