API requires field ID numbers, will not match field names itself

[marksherman]

User of the API must fetch the fields via API in order to get each field's hidden ID number, and then upload with that stringified number as the column key instead of the actual name.

The failure mode is unclear, as no exceptions are raised, no errors are returned. The only clue is the data set object returned from the call has a .getData() response of an empty list.

The server apparently registers data received, but does not put any into the project.

Does NOT work:

{'TMP': [1],
'SHK': [0],
'SP1': [1],
'SP2': [2],
'SLL': [3],
'seconds_elapsed': [222],
 'interval': [42]}

DOES work:

{'14446': [1],
'14442': [0],
'14443': [1],
'14444': [2],
'14445': [3],
'14441': [222],
'14440': [42]}
