Adding to what @ChethanYM said, shared traces can also arise from third party tool while connection gets closed abruptly or issue with proxy host/knox if you are using one in JDBC connection settings. If you would like more debugging on this, appending JDBC driver DEBUG logs would be helpful. To do so, add below with JDBC connection string and repro the issue , It will generate driver DEBUG logs and may give some more details about the issue.

@Rothmny  Based on what you have shared, you should be able to accomplish this with  GenerateFlowFile and ExecuteStreamCommand processors. The GenerateFlowFile processor would be configured to generate a 0 byte FlowFile and scheduled using Cron so that it creates a FlowFile on your required schedule that will then trigger the execution of the ExecuteStreamCommand processor that will execute your python script. For calling rest-api endpoints via NiFi dataflows, you could use the InvokeHTTP processor.  Since the InvokeHTTP processor does not require and inbound connection, you could just have it as first processor in a dataflows scheduled with cron as well.  Or, if the invokeHTTP is called after your script successfully executes you could trigger with the FlowFile that exited the the ExecuteStreamCommandProcessor.
