How to get 'rid' of indexing error, and how it came there

[Lars Corneliussen]

How to get rid of such an error without having to reset the whole index?

I did already resave the doc... If it is still an issue, shouldn't also the error come up again?

Or is the doc not watched anymore?

[Michael Yarichuk]

Looks a bit weird. Can you show the index definition?

Does this reproduces?

Also, can you check for full stack trace of this exception?

That is by design, actually. The error is in the _index_, which allows it.

The error will be removed if the index definition is updated

The given key was not present in the dictionary.

How can this error happen without a single square-bracket / dictionary-access in the index definition?

Stacktrace would be helpful - but I know, not too easy with Linq.

[Oren Eini (Ayende Rahien)]

Look at the logs, the full error is there

[Oren Eini (Ayende Rahien)]

Note that this error was raised by an index batcher, not the index itself

[Lars Corneliussen]

In the error logs I only found these errors and warnings (which I neither understand)...

But the times of occurance do not correlate.

This all looks like stuff that happens if you deleted an index while it was indexing.

[Lars Corneliussen]

The "index can't be found"-errors happened at 03:06 AM - hopefully I wasn't sleepwalking.

[Oren Eini (Ayende Rahien)]

Can you check the logs for what index that was?

It is possible that an idle index was deleted by the db.

[Lars Corneliussen]

hm. i still have these errors. now with an index that doesn'f have a scripted index result script attached at all!

this is in the logs....

You are using scripted indexes, but I don't see any way for this error to happen there, see:
