Unable to retrieve preview for CSV file

Hey All.

 

I'm attempting to fetch an HTML preview for a CSV file using the `/get_preview` endpoint.  Unfortunately I'm receiving back an `unsupported_extension` error.  Maybe my understanding is wrong? Appreciate any suggestions.

Reviewed the following documentation:

Dropbox `get_preview` Documentation 

Curl request using 'get_preview' resulting in error:

vagrant@vagrant:$ curl -X POST https://content.dropboxapi.com/2/files/get_preview \
     --header "Authorization: Bearer [truncated]" \
     --header "Dropbox-API-Arg: {\"path\": \"/items/24157/18365.catalog-items.csv\"}"

{"error_summary": "unsupported_extension/", "error": {".tag": "unsupported_extension"}}

 

Curl request using 'download' resulting in success:

 

vagrant@vagrant:$ curl -X POST https://content.dropboxapi.com/2/files/download \
     --header "Authorization: Bearer [truncated]" \
     --header "Dropbox-API-Arg: {\"path\": \"/items/24157/18365.catalog-items.csv\"}"

"created_at", "currency", "description", "discountable", "id", "metadata", "name", "object", "taxable", "taxes", "type", "unit_cost"
{...}
"1546048185", "usd", "Overpayment on order after adjustments", "", "overpayment-reconciliation", "", "OVERPAYMENT RECONCILIATION", "catalog_item", "", "", "", "0"

 

 

My understanding is that the API should return HTML data when requesting CSV files from the 'get_preview' endpoint.  

 

Thanks in advance.
