The error messages change resource each time it is run. I am using GitLab as a backend and my provider block looks like:

provider "fortiswitch" {
  hostname = "$redacted"
  username = module.global_variables.switch001_credentials.username
  password = module.global_variables.switch001_credentials.password
  cabundlefile = "ca.crt"
}

Any ideas?

Update: I am able to workaround this by using the -parallelism=1 flag

Hi @donnieelmore ,

Thank you for bringing this issue to our attention. I was able to reproduce it, and it appears that the problem stems from the FSW admin concurrent limitation. The default parallelism value in Terraform is set to 10, which may cause some admin sessions to reach the maximum concurrent limit for FSW. Based on my testing, setting the parallelism to 3 seems to be the optimal value for now. I have reported this to the development team for further suggestions.

Thanks, Maxx

Hi @donnieelmore ,

We are pleased to announce the release of Terraform FSW 1.1.3. Since the parallel tasks are limited by FSW restrictions, we would like to share a note regarding parallelism for your reference. Thank you for your assistance, and please feel free to reach out if you have any further questions.

Thanks, Maxx
