@Marvin, I am getting this error after upgrading Prefect to 2.20.15 from 2.19.8:

File "/usr/local/lib/python3.9/site-packages/kubernetes/client/api_client.py", line 292, in __deserialize
    klass = getattr(kubernetes.client.models, klass)
AttributeError: module 'kubernetes.client' has no attribute 'models'

The error you're encountering seems to be related to a change in the Kubernetes client library's structure, rather than directly with Prefect. It could occur if the client library has been updated but your code or Prefect's integration with Kubernetes hasn't caught up yet. Here are some steps and considerations to address this: 1. Update Dependencies: Ensure that your Kubernetes client library is updated to a compatible version. Sometimes, libraries may have breaking changes, and ensuring all dependencies are up-to-date can resolve such conflicts. 2. Kubernetes Integration in Prefect: The Prefect documentation doesn't mention direct changes related to this specific issue but does provide resources on configuring Kubernetes clients. You might want to check your configuration against the Kubernetes Credentials documentation. 3. Check for Breaking Changes: The Prefect 2.x documentation suggests that they strive to avoid breaking changes, but deprecated features do eventually get removed. Make sure that none of your existing configurations or integrations rely on such features. Check Prefect's versioning guidelines to ensure compatibility: Versioning and Compatibility. 4. Revisit Your Implementation: Double-check the part of your code where the Kubernetes client is being utilized, especially if there is any customization or specific handling that may not align with the newer library versions. If all else fails and the problem is persistent, it might be worth looking into Prefect's community forums or directly reporting this issue if it's not being addressed already. While I couldn't access GitHub issues directly, Prefect's GitHub repository might have some insights or community-reported solutions you can explore.
