Hi Ravi, We still need additional information to diagnose the problem. If this is still an issue for you, would you please check the Collation documents for the caseFirst field? Thanks, Danny |

Hello Ravi, Thank you for the extended logs. This invariant occurs when the caseFirst field in a Collation document is not set to one of the three values of "upper", "lower", or "off". Unfortunately I cannot tell against which namespace the query that triggered the problem was run. For any operations, indexes, or collections that have collations, can you please check the Collation documents for the caseFirst field to see if there are any discrepancies? Thank you, Danny |

Hi Kevin, It is just a simple aggregate project query. I have attached the query in txt file.amzissue.txt mongodb service stops as soon as we execute the query.

Hi Ravi, Thank you for the bug report, but the CXX project is for the MongoDB C++ driver. I'm moving this ticket to the SERVER project. Can you provide steps to reproduce this? What operations led to this invariant failure? Best, |
