migration crashes with workspace after getting remote state

[piizei]

I'm trying to create migration for remote state using terraform 0.13.6. Currently the migration crashes. Looks like it does not find the workspace anymore after getting the remote state.

Env: OSX
Dir: .
Terraform is inited with remote state

$terraform workspace show
cf
$ tfmigrate plan migration_1.hcl

Initializing the backend...

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

The currently selected workspace (cf) 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. default

Enter a value:

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

Hi @piizei , Thank you for reporting this!
The workspace has not been supported yet. See: #3

I'll close this as duplicated #3.
