Error when run Rover on Ubuntu and error 404 when checking Terraform Cloud Agent exist

[hanganhhung123]

1. An error occur when I run Rover on Ubuntu 20.04

in tfcloud.sh#539 file, function process_curl_response() has 2 lines to curl the TFE with token and redirect to STDERR by 2> >(tee /dev/stderr)

command="curl -sS -L -w '%{http_code}' --header 'Authorization: Bearer xxxxxx' --header 'Content-Type: application/vnd.api+json' $options -- '"${url}"' 2> >(tee /dev/stderr)"
debug "$(echo "Running command: $command")" >&2
command="curl -sS -L -w '%{http_code}' --header 'Authorization: Bearer  "$REMOTE_ORG_TOKEN"' --header 'Content-Type: application/vnd.api+json' $options -- '"${url}"' 2> >(tee /dev/stderr)"

When I try to do the migration to Terraform Cloud, below is the error I'm face with

tee: /dev/stderr: No such device or address
Error /tf/rover/tfcloud/tfcloud.sh on or near line 543; exiting with status 1

I have made some changes to remove the 2> >(tee /dev/stderr) out of tfcloud.sh and rerun the migration, it's worked.
So I need some help to remove the 2> >(tee /dev/stderr) in the code, or are there any other solution for it?

2. Terraform Cloud Agent Check failure

in tfcloud.sh#43, the function check_terraform_cloud_agent_exist() check if the tfcloud agent exist via url

url="https://${TF_VAR_tf_cloud_hostname}/api/v2/organizations/${TF_VAR_tf_cloud_organization}/agent-pools"

or

url="https://${TF_VAR_tf_cloud_hostname}/api/v2/organizations/${TF_VAR_tf_cloud_organization}/agent-pools/${gitops_agent_pool_id}"

When I run the Terraform Cloud migrate/plan/apply with agent mode, it throw this error:

Gracefully continue on error: HTTP status code is 404 for https://*****.com/api/v2/organizations/*****/agent-pools/apool-*****
apool-*****

Base on the latest api-docs from Harshicorp to list agent, the valid format of the url must not have the suffix /organizations/${TF_VAR_tf_cloud_organization}. It has pass from my testing also.
I need some help to fix it for latest run.

Can you check the user running the rover has permission to /dev/stderr?

ls -l /dev/stderr

Hi @LaurentLesle, The agent is runing with root user and it can access to /dev/stderr as bellow.

I found out that /dev/stderr is equivalent with &2. On linux, write to &2 works for every user; write to /dev/stderr works only for root users. I don't know why root user cannot write standard error into stderr.
I have make some test to replace 2> >(tee /dev/stderr) by 2> >(tee -a >&2) and the error gone
