@Marvin I have a secret in AWS that I access in prefect via an AWS credentials block. I have added a new key-value pair to the secret itself in AWS, but now all my attempts to access it fail with the following error:

TypeError: 'NoneType' object is not subscriptable

. Do I need to update the prefect block somehow, or is something else going on?

The error you're encountering,

TypeError: 'NoneType' object is not subscriptable

, suggests that the code is attempting to access an element of a

None

object, which is not possible. This often happens when the expected data is not being retrieved correctly. Here are some potential solutions and considerations based on the Prefect 3.x documentation: 1. AWS Secret Block Configuration: Ensure that the AWS Secret block in Prefect is correctly configured with the new key-value pair. You might need to update the block to reflect the changes made in AWS Secrets Manager. If the block was created through the Prefect UI, you can update it there. If it was created via code, you might need to recreate or update the block to include the new key. 2. AWS Credentials Block: Verify that your AWS Credentials block is correctly set up with the necessary permissions. This block should have access to read the updated secret from AWS Secrets Manager. 3. Asynchronous Context: If you're working within an asynchronous task or flow context, ensure that you are properly awaiting asynchronous functions. Prefect's block loading methods can be asynchronous, so if you're not awaiting them, you might encounter

NoneType

errors. You can use

_sync=True

if needed to ensure synchronous behavior. 4. Check for Errors in Secret Retrieval: Double-check that the secret retrieval code is correctly accessing the updated secret. Ensure that the secret name and key names are correctly specified. You can find more details on managing AWS secrets in Prefect here. If the problem persists, it might be worth checking your code for any assumptions about the data structure that might have changed with the new key-value pair.
