On version 7.0.6, MongoDB aggregation pipelines containing all of the following:
- $sort
- $skip
- $limit
- either $lookup or $group after sort-limit-skip
will fail with the following error:
{code: 8349205 codeName: Location8349205 errmsg: Limit code returned unexpected value}
This was an issue in the Slot Based Execution (SBE) query engine that affected $sort operations with a set limit. By default we only execute $lookup and $group in SBE, so the issue only affects aggregations containing these stages.
As an immediate solution, users can do either of the following:
- Downgrade to version 7.0.5
- Disable SBE by setting the internalQueryFrameworkControl parameter to “forceClassicEngine”. This option may come with performance regressions.
db.adminCommand({setParameter: 1, internalQueryFrameworkControl: "forceClassicEngine"})
MongoDB versions 5.0, 6.0 and Rapid Release 7.2 are unaffected.
This issue is fixed in MongoDB 7.0.7.
