Hello. I'm using

Prefect 2.7.3

with

prefect_aws 0.2.3 prefect-snowflake 0.25 prefect-sqlalchemy 0.2.2

on windows (running locally for now), and when I run my flow, I get these 3 warnings first (even when I don't use them)

Warning!  Failed to load collection 'prefect_aws': ImportError: cannot import name 'CredentialsBlock' from 'prefect.blocks.abstract' 
Warning!  Failed to load collection 'prefect_snowflake': ImportError: cannot import name 'CredentialsBlock' from 'prefect.blocks.abstract'
Warning!  Failed to load collection 'prefect_sqlalchemy': ImportError: cannot import name 'CredentialsBlock' from 'prefect.blocks.abstract'

And when I use

secret_reader

in my flow, I get this error:

from prefect.blocks.abstract import CredentialsBlock
ImportError: cannot import name 'CredentialsBlock' from 'prefect.blocks.abstract'

Any ideas what might be the problem? Thanks

Hi @Mansour Zayer The abstract block types (

CredentialsBlock

being an example) were added to prefect core in

2.7.4

, and those collections you are trying to install use the

CredentialsBlock

to define their respective credentials blocks can you upgrade to

prefect>=2.7.4

?

Yes, that solves it thanks. Is there another way to read AWS secrets manager secrets in prefect <=2.7.3? I'd have to use the boto core library?
