@Marvin When I run

prefect deploy

I am getting error

TypeError: object of type 'NoneType' has no len()

. Other prefect commands work like prefect version. I am in correct prefect cloud and workspace. No issues with prefect.yaml file either as it works fine for my colleague. Why does

prefect deploy

not working?

this is an issue with one of our dependencies,

typer

It seems there are no open issues on GitHub related to this specific error with

prefect deploy

. The error you're encountering suggests that the command is trying to check the length of an object that is

None

, possibly due to a configuration or environmental difference between your setup and your colleague's. Since the issue doesn't seem to be reported, you can try the following steps to troubleshoot the problem: 1. Environment Consistency: Ensure your Python environment is consistent with your colleague's, including dependencies and their versions. Use

pip list

or

conda list

to compare. 2. Prefect Version: Make certain you're running the same version of Prefect as your colleague by running

prefect version

. 3. Prefect Configuration: Double-check that your Prefect configuration files and environment variables are set up correctly. Sometimes subtle differences can cause issues. 4. Authentication: Verify that you're authenticated with the correct Prefect Cloud tenant and workspace. 5. Permissions: Make sure you have the necessary permissions to deploy flows to the designated workspace in Prefect Cloud. 6. YAML File: Even if the

prefect.yaml

file works for your colleague, validate the file's syntax and structure just in case, especially if it references any local resources or paths. 7. Debug Mode: Run the command in a verbose or debug mode to gather more information about the step that's failing. You may find an additional option in the CLI to increase verbosity or you can set up logging in your environment. If the issue persists, you could consider raising a new issue in the Prefect GitHub repository or asking for help on the Prefect Discourse community, providing more details about the error and your environment. Since this is a somewhat general approach, if you feel like you need more targeted assistance, you could provide me with additional information such as your Prefect version and any other errors displayed, and I can attempt to search further.

I think upgrading should fix it now but I'm not 100% sure. are you able to upgrade your prefect version?

My colleague is using prefect version 2.12.1 and works fine

can you try

pip install typer==0.12.1

?

Still didn't work

what do you see if you do

pip freeze | grep typer

?

🤔

We have support with Prefect. Should I work with that?

can you try

pip install -U typer --force-reinstall

?

still doesn't work

do you have more of the trace?
