This happens when a user requests data for a one period, e.g. 2020-10-20 -> 2022-11-21 and there is data but its for a period of time that ends prior to the start date requested.
Because the following section is replacing the users requested start date with the last recorded datetime
openaq-api-v2/openaq_fastapi/openaq_fastapi/routers/measurements.py
Lines 291 to 293 in 0444018
This results in an end date that is before the start date, which leads to a negative count of seconds for the duration which then leads to a negative count of total measurements. The following sections show the calculation of seconds and then how its used to get the (estimated?) total count.
A fix to this might simply be to add the requested start/end times to the initial query here
from openaq-api-v2.
