Gracefully return [] to an incorrect query with from=datapoints and empty select.value #120
Description
mountain chart sends a query with empty "select.value" array to Billy dataset
To which ddfcsv reader in small waffle errors and pollutes the error log. Returns 500.
2024-07-11T14:54:52: Too many query structure errors:
2024-07-11T14:54:52: * 'select.value' clause for 'datapoints' queries must have at least 1 item undefined
2024-07-11T14:54:52:
2024-07-11T14:54:52: InternalServerError: Internal Server Error
Big-waffle would gracefully return an empty array in this case (try)
Response:
{
"version":"bb66a61",
"header":["person","time"],
"rows": [
]}
It is better that DDFCSV reader would also return an empty array in this case without complaining
