RangeError ERR_OUT_OF_RANGE

[nsantini]

I keep getting these errors but I can't figure out what SSB call is triggering it. Might be from a plugin running in the background...

internal/buffer.js:83
  throw new ERR_OUT_OF_RANGE(type || 'offset',
  ^

RangeError [ERR_OUT_OF_RANGE]: The value of "offset" is out of range. It must be >= 0 and <= 5. Received 22

Thanks for the stack trace. First we need more details:

• Version of ssb-db2 used
• Version of jitdb used
• Version of async-append-only-log used

And then it would be helpful if you would tell us what kind of operators you used, because this error stack trace should only happen with a prefix index, so it's one of these:

https://github.com/ssb-ngi-pointer/ssb-db2/blob/a039325205ab1a6bbe31c7cbf1e54390aa088cb6/operators/index.js#L64

Given that your error says 22, it might be this https://github.com/ssb-ngi-pointer/ssb-db2/blob/a039325205ab1a6bbe31c7cbf1e54390aa088cb6/operators/index.js#L65 but what's odd is that it's happening on a field that is only 5 bytes long, which is very odd. It means that the msg.value.author is 5 characters long, which is totally weird.

Which is why it would be helpful to know how you're writing your queries.

Hi @staltz , sorry about the delay, I don't seem to have notifications configured for GitHub 😅

Here are the versions:

• ssb-db2: 3.1.0
• jitdb: 6.0.0
• async-append-only-log: 4.1.0

The queries I'm running are pretty basic:

• ssb.threads.thread({ root: msgId, allowlist: ["post", "blog"] })
• ssb.db.getIndex("aboutSelf").getProfile(feedId)
• ssb.db.getIndex("aboutSelf").getProfiles()
• ssb.threads.private({allowlist: ["post", "blog"]})
• ssb.threads.publicSummary({ allowlist: ["post", "blog"] })
• ssb.blobs.get(blobId)

Thanks. I'm trying to figure out where is the prefix index used. Can you do an ls -la on the db2/indexes folder? That should show us which indexes you're using and which one is a prefix (or prefix map) index, which the stack trace refers to.
