Hi #prefect-aws I am trying to execute my flow which is uploaded to s3 storage from a remote agent in a laptop in some other location. Getting this error. Any help would be great. Thanks

Flow could not be retrieved from deployment.
Traceback (most recent call last):

Can you share the code that led to this error?

If you are using

s3-bucket

from

prefect-aws

instead of the regular

s3

block that is built into Prefect, you will need to install the

prefect-aws

package on your agent machine, otherwise you will get the error you see here.

^It works now. Thanks Ryan :)

You're welcome! I'm happy to hear it is working now 😄
