Description

The storeLastError queue configuration option is deprecated as of CDS 10 and will be removed in cds^11. In CDS 10 the option is still accepted and has no changed behavior, so this is not an immediately breaking change. However, projects that leave storeLastError in their queue configuration will encounter an error after upgrading to cds^11. Teams should remove the option now to avoid a forced migration under time pressure during the next major upgrade.

How to Check

• [ ] Search package.json and .cdsrc.json for storeLastError inside any queue or outbox configuration block.
• [ ] Run cds env and check for storeLastError in the resolved configuration output.

Migration Steps

1. Locate occurrences of storeLastError in queue configuration:

 "cds": {
   "requires": {
     "my-queue": {
-      "storeLastError": true
     }
   }
 }

2. Remove the storeLastError key. If the option was used to persist error details for observability, consult the CDS 10 queue documentation for the replacement mechanism (e.g. dead-letter queue inspection or structured error events).

3. Test queue failure scenarios after removal to verify that error visibility is maintained through alternative means.

Notes

This change is not breaking in CDS 10. The entry is included so that projects can proactively clean up deprecated config before the cds^11 removal makes it mandatory.
