I am a beginner in Google App Engine. I am trying to get the data of Klaviyo from Flask to Google Cloud Storage. When I run the code at my computer, everything runs very well, but after I push all my code in the Google Server, the data always gets null. In the code, I have had to calculate the values and I get integer and float data types. I tried to change schema, but the code does not work in the server. Then I convert it into string types, and the same problem occurs.
