Docs say apiVersion is optional, but it is required to connect about loopback-connector-elastic-search HOT 4 CLOSED

v1.0.8 has been released with a documentation update. Thank you for reporting the problem @diekeure

Tested with version 1.0.7

Yes correct, we added support for deleteByQuery for es v2.x and the code needs to decide how to operate for v1 versus v2 and for that we look at the apiVersion field ... will think about it more and either fix the docs or the code.

As a workaround, please continue to specify the apiVersion and thank you for reporting this.

Overtime the default_api_branch": "2.3" and apiVersion will continue to be a moving target.

Since we don't have quick access to that property in the code when we need to make decisions based on version, for example: if (self.settings.apiVersion.indexOf('2') === 0) { ... lets just make apiVersion required in the docs.
