Integration: Marketo with Taxi for Email

Has anyone integrated Marketo with an Email design platform, Taxi for Email (https://taxiforemail.com/)?

We have the integration set up but when we try to export an email to Marketo, we are running into a few issues of trying to pass:

When we are trying to create a brand new email, we are getting this export error message:

711: 6314 Folder is not an email template folder

When trying to update an existing email in Marketo, we are getting this error message:

1001: Invalid value ‘%s’. Required of type ‘%s’ Error is generated whenever parameter value has type mismatch. For example string value specified for integer parameter.

any thoughts or recommendations
