I am running the flow on a infrastructure on docker container docker hosted on dockerhub But I think the issue starts even before attempting to communicate with dockerhub

Khuyen Tran · Answer

Are you using Cloud 2

Deceivious · Answer

2 1 1

Khuyen Tran · Answer

Just to make sure I m on the same page you got this error when running `prefect agent start` right

Deceivious · Answer

No

Deceivious · Answer

After i run a flow

Khuyen Tran · Answer

you mean running `python path to your flow`

Nate · Answer

< Deceivious> did you register your own version of the DockerContainer infra block

Deceivious · Answer

yes the dockerfile content is ```FROM prefecthq prefect 2 latest RUN python m pip install adlfs```

Nate · Answer

what I mean to ask is somewhere in your project did you do ```from prefect blocks core import Block class DockerContainer Block custom implementation``` and then ```prefect block register m your module where block definition is``` because looking at this ```UserWarning Block document has schema checksum sha256 cc5fd7bf7e129ced2bf2b25cb0fac04e0c0596464bb5a001c699ddf43d05f752 which does not match the schema checksum for class DockerContainer This indicates the schema has changed and this block may not load ``` it looks like the block definition for `DockerContainer` is invalid
