N1QL + SEARCH clause with named parameter results in runtime error

Vinaya_Kumar_B · June 8, 2022, 12:25pm

Dear all,

We ran into following issue with Couchbase Community Edition 7.1.0 build 2556.

N1QL with SEARCH clause works without named parameter.

However, it fails if a named parameter is used.

Runtime Error:

[
  {
    "code": 5001,
    "msg": "Panic: runtime error: invalid memory address or nil pointer dereference",
    "query": "SELECT meta(r).id\nFROM resources r\nWHERE SEARCH(r, $query, {\"index\":\"search-index-v1\"})\nLIMIT 1;"
  }
]

Are named parameters supported in SEARCH clause of N1QL?

It shouldn’t be panicking; could you share the details (stack) from the query.log ?

vsr1 · June 8, 2022, 1:38pm

As @dh mentioned it should not panic. Provide stack we will fix that.

Try this

SELECT meta(r).id
FROM resources r
WHERE SEARCH(r, {"query":$val }, {"index":"search-index-v1"})
LIMIT 1;

@Vinaya_Kumar_B need more information from you here.

I see where you’re setting $query but I don’t see the index definition you’re using.

And in case of panics - sharing the stack trace or logs is quite necessary for us to debug. You should be able to download logs for your couchbase node(s) from the Logs tab on your console.

Thanks for reporting this.

I’ve created a ticket - https://issues.couchbase.com/browse/MB-52476
I was able to reproduce and verify the fix, we’ll include this fix in our next release.

This was the commit that introduced this regression - https://review.couchbase.org/c/n1fty/+/169777
So you should look into picking up a build older than 7.1.0 - perhaps 7.0.3 if possible until 7.1.1 becomes available.

Vinaya_Kumar_B · June 9, 2022, 4:47am

@abhinav Thank you for the update that this issue would be resolved in 7.1.1.

Vinaya_Kumar_B · July 22, 2022, 2:41pm

@abhinav How can I check the status of the ticket created in this thread - https://issues.couchbase.com/browse/MB-52476.

The ticket seems to be no longer accessible unlike other tickets in the release notes here. Was this ticket reference changed?

abhinav · July 22, 2022, 3:07pm

Hi @Vinaya_Kumar_B. Turns out we were a little late per the release cycle for 7.1.1.
So the fix is going to be included in 7.1.2 - which is due end of August.

p.s. Loading... should be accessible again.

Vinaya_Kumar_B · July 26, 2022, 4:37am

Thanks for the update @abhinav .
