### Apache StreamPipes version dev (current development state) ### Affected StreamPipes components Backend ### What happened? The endpoint for data lake measurements allows to filter the data records when querying for a specific measurement. Hereby, you define a time window for which you want to get data by specifying `startDate` and `endDate`. If you choose both parameters so that there are no records matching your criterion in the data lake, the API returns no data series in the response like the whole measurement would not exist. ### How to reproduce? Query the API endpoint `/api/v4/datalake/measurements/<identifier>` and extend the query by `?startDate=valueStart&endDate=valueEnd`. Choose `valueStart` and `valueEnd` in such way that there are no entries for targeted measurement in the corresponding time frame. Eventually, the API returns a response with no data series indicating the whole measurement does not exist. ### Expected behavior Return the metadata of the data series but with an empty array for `rows` so that it clearly indicates that the actual measurement exists but there is to data available for the given query. ### Additional technical information _No response_ ### Are you willing to submit a PR?
