cubejs-elasticsearch-driver not compatible with v7.x

[gabri94]

Describe the bug
The backend package works with elasticsearch up to v6.8. With v7.x it causes the following error:

ResponseError: illegal_argument_exception
    at onBody (/cube/node_modules/@elastic/elasticsearch/lib/Transport.js:337:23)
    at IncomingMessage.onEnd (/cube/node_modules/@elastic/elasticsearch/lib/Transport.js:264:11)
    at IncomingMessage.emit (events.js:326:22)
    at endReadableNT (_stream_readable.js:1241:12)
    at processTicksAndRejections (internal/process/task_queues.js:84:21)

I've tested this behaviour both with elastic.io and a local vanilla elasticsearch v7.15 image.
On the other hand, the library works correctly with elasticsearch v.6.8.18

To Reproduce
Steps to reproduce the behavior:

• Deploy elasticsearch v7.15 using docker.
• Try to connect cube.js by following the instructions on the wiki
• Open the cube.js schema and see the error.

Expected behavior
The lib should work with the latest version of elasticsearch

By further investigating it looks like at line 134 tries to cal getMapping on the index '.geoip_databases', which causes the exception.

In version 6.8 this caused an error, but the || {} was sufficient to make it work. In v 7.15 this causes the illegal_argument_exception errror.

I came up with this fix

If you think it's ok, I will open a PR

Hey @gabri94 ! PR would be very much appreciated!

[stueccles]

Any chance of getting this merged in? @gabri94 fix seems to work with Elastic Cloud which is running on 7.16

[paveltiunov]

@stueccles @gabri94 We just need a PR here.

[AlbanCrepel]

Any update on the PR @gabri94 ?

[gabri94]

The fix is only partially working, so It doesn't make sense to merge it.

issue still persist (trying with ElasticSearch 7.15)

[shivam145]

i had made changes as present in @gabri94 's PR and also added a small tweak in one of the line as shown below and it worked for me in version 7.14.1

const props = mappings.body[index].mappings.properties || {};
@nassima-creator please can you try to connect to elastic 7.15 with the mentioned changes
