Acceptance Criteria

• The error messages related to missing index-pattern-fields (package.type, package.name) are resolved.
• All dashboard widgets display data correctly without errors.

• Code changes implemented to fix the bug.
• Peer or lead developer has reviewed the changes.
• Unit tests written and passed.

Facing this issue

[MarantosGeorge]

Implemented in Dev, testing before deploying to Prod.

Create a local cluster with data from our prod env, try to upgrade it, before we'll have a conclusion

[ArmandMeppa]

Was able to backup the prod cluster configuration and partial data to a local cluster, then emulated the upgrade process.
The process went smootly, with the result cluster and dashboards working well.

@MarantosGeorge will replicate the same process on his side to confirm the result
