Missing function destroyAll() ?

[JuergenSimon]

Hello,

I am using the loopback-connector-esv7 and followed the instructions here: https://www.npmjs.com/package/loopback-connector-esv7

In my code, I'm using the destroyAll() method on some entities. Unfortunately I am getting the following error message after switching to loopback-connector-esv7:

(node:7797) UnhandledPromiseRejectionWarning: AssertionError [ERR_ASSERTION]: destroyAll() must be implemented by the connector

How do I fix this?

Update: this function turned up when I did the following steps:

• Instead of using "connector": "es" I used "connector": "esv7" in the datasource configuration.
• This provoked an error with "apiVersion":"7.0". I had to set this to "apiVersion":"_default" to avoid an error message claiming this apiVersion was not supported.

Now the application starts, but a lot of things are not working:

• None of the data 'saved' with attached models using the create method for example persists in the index.
• The automigrate function does not create the index.
• My mappings have different indexes for different entities. This is broken. I had to patch one of the connector's methods to force it to respect the specific index (as it's written in the documentation). The method in question is ESConnector.prototype.addDefaults, where I discovered some stub code doing this job commented out!
• Accessing an empty index results in errors, such as: Failed with error: [query_shard_exception] No mapping found for [_id] in order to sort on, with { index_uuid="Fccr_0hjQe-wTa9jk8sicg" & index="appics.customer" } { [query_shard_exception] No mapping found for [_id] in order to sort on, with { index_uuid="Fccr_0hjQe-wTa9jk8sicg" & index="appics.customer" } :: {"path":"/appics.customer/ESCustomer/_search","query":{"size":1,"from":0},"body":"{\"sort\":[\"_id\"],\"query\":{\"query_string\":{\"query\":\"id:42\"}}}","statusCode":400,"response":"{\"error\":{\"root_cause\":[{\"type\":\"query_shard_exception\",\"reason\":\"No mapping found for [_id] in order to sort on\",\"index_uuid\":\"Fccr_0hjQe-wTa9jk8sicg\",\"index\":\"appics.customer\"}],\"type\":\"search_phase_execution_exception\",\"reason\":\"all shards failed\",\"phase\":\"query\",\"grouped\":true,\"failed_shards\":[{\"shard\":0,\"index\":\"appics.customer\",\"node\":\"2etbhi8zQzSyouSFsQGmrw\",\"reason\":{\"type\":\"query_shard_exception\",\"reason\":\"No mapping found for [_id] in order to sort on\",\"index_uuid\":\"Fccr_0hjQe-wTa9jk8sicg\",\"index\":\"appics.customer\"}}]},\"status\":400}"}

@JuergenSimon connector-es is deprecated. I've updated loopback-connector-esv6 @2.0.0 plugin to support both Elastic versions 6 and 7. Same code is merged in master branch of this repository, please check updated README and examples/server/datasources.json file for sample.

destroyAll is working as expected in this version.

@bharathkontham Right now, the doc says This connector will only connect to one index per datasource. My project has two indexes for mappings originally. How should I configure it?
