@Marvin I have a prefect 2 task with the following definition:

@task(
    task_run_name="my-task",
    retries=5,
    retry_delay_seconds=exponential_backoff(backoff_factor=10),
    tags=["my-api-tag"],
)
def my_task(category_id: str) -> list[dict]:
    ...

The task calls an external API, and sometimes gets throttled, so it raises an HTTP exception because it gets a 429 response. In this case, the task retries, but I can see in the logs that it's only retrying once - not 5 times. If the first and only retry fails, the whole task just ends with a "Failed" status. Why isn't the task being retried more than once?

It seems that your task's retry behavior might be affected by the configuration of the

exponential_backoff

function. The

exponential_backoff

utility generates a list of retry delays, and its behavior can be influenced by factors like the

backoff_factor

and the maximum number of retries. Here are a few things to check: 1. Exponential Backoff Configuration: Ensure that the

exponential_backoff

function is configured properly. The

backoff_factor

you provided is 10, which means the delay between retries will grow exponentially, but it should not affect the number of retries. However, if the function is not returning the expected list of delays, it might be causing the task to retry only once. 2. Retry Condition: If you have any custom retry logic, such as a retry condition function, ensure it's not inadvertently restricting retries. Prefect allows you to define custom retry conditions that determine whether a task should retry based on the exception raised. 3. Global Settings: Check if there are any global settings that might be overriding your task-specific settings. Prefect allows global retry configurations that can affect task behavior. For more details, you can refer to the Prefect 2.x documentation on task retries and exponential backoff. If everything seems correct, you might want to log the retry delays to verify that they are being generated as expected. If issues persist, consider reaching out to the Prefect community or checking for similar issues on their GitHub repository.
