Error when creating a Datetime Partitioning Spec in REST API

[cpg]

Hello all,

I have been able to successfully run a time series model through the python API with relative ease:

partitioning_spec = dr.DatetimePartitioningSpecification(

'DT', use_time_series=True, multiseries_id_columns=['Source'])

project.set_target('Value', partitioning_method=partitioning_spec)

---

I have not, however, had the same success using the same data and the same techniques (at least as far as I can tell) using the REST API:

{"useTimeSeries", true,

"datetimePartitionColumn", "DT",

"multiseriesIdColumns", ["Source"]}

I encounter the following error, which I can't find discussed online and cannot wrap my head around what it could be trying to tell me:

error{"message": "Column DT has not been analyzed for time series modeling with the specified multiseries id columns ['Source']."}

---

For reference, my test data looks like this:

DT                     Source   Value

01-01-2000      f1            1

01-01-2000      f2            100

01-02-2000      f1            2

01-02-2000      f2            105
