Couchbase Lite for iOS: Database Integrity Check Failures about couchbase-lite-ios HOT 4 OPEN

I've opened CBL-5564 to track this issue.

Questions:
What version of CBLite are you using to perform this "integrity check"
Is the integrity failure visible from whatever application created this DB? Can we see the logs?
Can we have a copy of the database? You are welcome to sanitize it, of course, as long as the sanitized version still has the issue.

It's not clear what is leading into the index missing row issues. From what I knew, we once have an issue (already been fixed) upgrading from 2.8.x to 3.x.x which could result in the invalid database format due to some mismatched data type in the index. You may upgrade to 3.1.6, delete, and recreate the index to see if the issue is resolved.

@bmeike thank you for your reply.

We utilized Couchbase Lite version cblite tool 2.8 EE:

❯ cblite --version
Couchbase Lite Core 0.0.0-EE (df1951bf+e2588435+)

Additionally, we conducted an integrity check within the iOS app using the following method, encountering the same error observed with the CBLite tool:

try messageStore.performMaintenance(type: .integrityCheck)

Hi @shamim-ict ,
As Blake mentioned, it would be a great help to have verbose logs alongside with a sample db with the issue you are mentioning.

We have tests in place for performMaintenance that are passing for current release and without more context of what is leading into index missing row issues, it will be very hard to understand what is going on.

I must say that 2.8 is End-of-Life - https://www.couchbase.com/support-policy/enterprise-software/ - so this won't be prioritised unless it can reproduced on 3.0 onwards.

Can you please upgrade to, at least, 3.0 and check if the issue is still persisting?
