Hey @wangrg, great to see you back! Hope all's been well since our last chat.

Based on the information provided, it seems like the issue might be related to some changes in the codebase between versions v0.3.34 and v0.5.9. However, without access to the specific changes made in the api/controllers/console/app/model_config.py and api/controllers/console/app/app.py files between these versions, it's difficult to pinpoint the exact cause of the problem.

One possibility could be that there were changes in the way the application handles the publishing and editing of apps, and these changes are not compatible with the data or configurations from the older version. This could potentially cause the application to fail when trying to publish or edit apps.

Another possibility could be that there are new dependencies or system requirements in version v0.5.9 that were not required in version v0.3.34. If these new requirements are not met, it could cause the application to fail.

To help narrow down the cause of the problem, could you please provide more information about the error messages you're seeing when the deployment fails? Additionally, could you please provide the specific changes made in the api/controllers/console/app/model_config.py and api/controllers/console/app/app.py files between versions v0.3.34 and v0.5.9?

Also, it would be helpful if you could provide more details about your environment, such as the operating system and version, the version of Python you're using, and any other relevant information.

Finally, if you could provide a more detailed description of the steps you're taking to reproduce the problem, it would be very helpful. For example, what specific actions are you taking in the application when the failure occurs? Are there any specific apps or data that cause the failure, or does it happen with any app or data?

This information will help us better understand the problem and find a solution. Thank you for your cooperation.
