Solutions

1. Set end_date to today or an earlier date; future end dates are not allowed.
2. Remove the end_date argument to default to the current date.

When it happens

Trigger: This error is raised at scripts/data_collector/yahoo/collector.py:796 when the guard condition fails: "end_date is greater than the current date". It triggers when the code path receives input or a state that violates the precondition checked at this point — e.g. an unimplemented abstract method being called, an unsupported argument type/value, or an invalid configuration. To avoid it, satisfy the documented precondition before this call: implement the required method in your subclass, or pass a supported value of the expected type as described by the message.

Common situations: See trigger scenarios.
