Initializing the backend...

Successfully configured the backend "remote"! Terraform will automatically
use this backend unless the backend configuration changes.

The currently selected workspace (default) does not exist.
  This is expected behavior when the selected workspace did not have an
  existing non-empty state. Please enter a number to select a workspace:
  
  1. production
  2. staging

  Enter a value: 

Error: Failed to select workspace: input not a valid number

related hashicorp/terraform#21393 ??

I could fix it by using TF_WORKSPACE

[sudomateo]

Good point! Using TF_WORKSPACE is the preferred method. Glad you're unblocked for now.

[sudomateo]

I tested the TF_WORKSPACE environment variable. It's currently the best method to select a workspace during automation.

After following the thread to the bottom a concoction of all your ideas will work.

desired_workspace="test"
export TF_WORKSPACE="default"
terraform init -input=false
# without unsetting the env var it will bork workspace selection command
unset TF_WORKSPACE 
exists=$(terraform workspace list | sed $'s/\r//' | grep -E "(^|\s+)${desired_workspace}$" > /dev/null 2>&1; echo $?)
if [ "${exists}" = "0" ]; then
  terraform workspace select ${desired_workspace}
else
  terraform workspace new ${desired_workspace}
