Checklist:

• I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• I've included steps to reproduce the bug.
• I've pasted the output of argocd version.

Describe the bug

If you have fields that are set to default (see below for examples) argocd will say app is OutOfSync and try to sync even though the diff is blank

ignoreDifferences: []
fileParameters: []
ignoreMissingValueFiles: false
passCredentials: false
skipCrds: false
valueFiles: []

To Reproduce

Enter above fields as defaults instead of leaving them out, argocd will want to sync even no changes

Expected behavior

Does not sync

Screenshots

Version

argocd-server: v2.8.4+c279299

Note: This did not go OutOfSync in 2.7.7

Logs

Before updating the yaml file:
argo-cd-before.txt

After, this is when it wants to sync:
argo-cd-after.txt

Application shows blank diff:

We are experiencing the same on the same version. Also some resources are labeled missing and out of sync, even though they do exist in the cluster and do have a live manifest.

noticing the same issue with argocd v2.10.7

I have also tried experimenting with the resource tracking using all three methods from this guide: https://argo-cd.readthedocs.io/en/stable/user-guide/resource_tracking/#resource-tracking

Despite my best efforts, it is still showing the same for multiple applications.

Status: OutOfSync
Health: Missing

same, probably related to #15126

We noticed this issue when doing a fresh rollout. But we migrated from values: | to valuesObject meanwhile, hence this was super confusing.

Reverting back to values: | made argo do a proper sync. Then again reverting back to valuesObject seems to work!

This issue is resolved for me after upgrading to v2.11.0
