Spacemk audit write to XLS - Unable to complete if 'tag-names' is a list of emtpy lists

[jeanvisser]

When the TF API returns workspaces data, if the 'tag-names' attribute is an empty list, the audit script errors:

TypeError: Unsupported type <class 'list'> in write() .

Traceback: audit_traceback.txt

Example:

curl -s \                           
  --header "Authorization: Bearer $TOKEN" \
  --header "Content-Type: application/vnd.api+json" \
  https://app.terraform.io/api/v2/workspaces/{WORKSPACE_ID} | jq ".data.attributes[\"tag-names\"]"
[]

Adding some additional output to the script, the value being passed to xlswriter:
Key, Value of pivoted_entity_type_data.items(): attributes.tag-names: [[], [], [], []].

Added:

if isinstance(value[0], list):
    break

To https://github.com/spacelift-io/spacelift-migration-kit/blob/main/spacemk/exporters/base.py#L168 as a workaround.
