Error with start date when ARBCreateSubscriptionController

[Ben_]

Section of code for start Date:

# Setting payment schedule
    paymentschedule = apicontractsv1.paymentScheduleType()
    paymentschedule.interval = apicontractsv1.paymentScheduleTypeInterval()
    paymentschedule.interval.length = 1
    paymentschedule.interval.unit = 'months'
    today = datetime.today()
    if today.month == 12:
        month = 2
        year = today.year + 1
    elif today.month == 11:
        month = 1
        year = today.year + 1
    else:
        month = today.month + 2
        year = today.year
    paymentschedule.startDate = datetime(year, month, 1).isoformat().split('T')[0]
    paymentschedule.totalOccurrences = 12
    paymentschedule.trialOccurrences = 0

Even though startdate is auto saved as "YYYY-MM-DD"

Date when being processed in : apicontrollersbase.py is: 2020-11-01 00:00:00

Resulting in error:

Have other's seen this error, I believe this is recent.

Thank you for the help.
