Using TextP with gremlin-javascript ends up with Server error (no request information): Invalid OpProcessor requested [null] (499)

[Vladimir Katansky]

Hello there,

I just tried to  use TextP and it seems like it simply doesn't work

```

g.V().has('country', TextP.containing('U'))

```

end up with an error:
```

Server error (no request information): Invalid OpProcessor requested [null] (499)

```

I use JanusGraph and connected to it via wss protocol

Does somebody face this kind of error before?

I don't know what that error is offhand, but we have a number of tests for TextP that are all passing:

https://github.com/apache/tinkerpop/blob/75b2ab2c589d26cdcf30e4d89433e4b58441b962/gremlin-test/features/filter/Has.feature#L562-L660 

Perhaps it's something related to your environment. I'd start debugging the problem by checking the version of TinkerPop that you are using on the client and the server and ensuring that they are the same.

 we solved it this way:

```
this.g.V().hasLabel('skill').has('name', new P('textContains', 'someth')).limit(10).valueMap()
```

huh - interesting workaround. i guess the failure makes sense now that i think about it. i don't think JanusGraph has an official release on 3.4.0 yet - that would explain the incompatibility.
