@jenwei Thank you for the update, regarding your question, there is no direct way to do it because this is not the purpose of the adapter, the purpose of the adapter is to be the “glue” between your site on Wix and your database.
but there is a way to save a “snapshot” of collections on your Wix site, open an external collection via the content manger and click the button with the three dots, it’s next to the add item button. (look at the screenshot below) and click on Export to CSV , then create a new collection in your site and import the items that you exported (you need to use the CSV file that you got from the export step)
Regarding the guide, I will ask the docs team to update the guide to include the missing environment variable.
