Container unable to install Paper

[goosenation]

Describe the problem

Startup logs show that the container is unable to install Paper. Some of the lines in the container log include this:

• [mc-image-helper] 16:20:03.830 ERROR : 'install-paper' command failed. Version is 1.41.9
• Caused by: me.itzg.helpers.http.ResponseParsingException: Failed to parse response body into class me.itzg.helpers.paper.model.VersionBuilds at me.itzg.helpers.http.ObjectFetchBuilder.lambda$handleResponse$1(ObjectFetchBuilder.java:87)
• Caused by: com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type me.itzg.helpers.paper.model.ReleaseChannel from String "ALPHA": not one of the values accepted for Enum class: [experimental, default]

Could this be related to the last commit of 2 days ago? last succesfull install was roughly 1 or 2 months ago. Server has been running with no issue until today.

Thanks.

You're running a very old copy of the image

[init] Image info: buildtime=2025-05-19T12:22:47.180Z,version=java21,revision=89a6e1ad88b192b31551c5f482425cde230fe775

Always re-pull the image before reporting issues.

[goosenation]

You are right, of course. A hole in my knowledge that has now been patched. The correct version was now pulled and installed.

Apologies, and thank you for your time and for your work.
