As you can see the path for the module that is running is /usr/local/lib/... whilst this module is looking for it in /usr/src/app/. This is because of this line:

https://github.com/nodkz/graphql-compose-elasticsearch/blob/master/src/ElasticApiParser.js#L126

which is seeking a path relative to the current directory, not the node module.

[nodkz]

Did you install elasticsearch package in your app?

[markbirbeck]

Would you not be better off finding the path by going relative to the elasticsearch module? Using https://nodejs.org/docs/latest/api/modules.html#modules_module_filename, for example.

Even better, is it not possible to use the ElasticSearch module itself to get the information you need?

const es = require('elasticsearch');
console.log(es.Client.apis);

Or is that information different to what you want?

[markbirbeck]

Yes, it's installed, but all modules are global. (It's in a Docker container.)

[markbirbeck]

So to be explicit, the /usr/local/lib path is what it should be, which as you can see in the error message is where all the other node modules are installed. But it's looking in /usr/src/app which is where the express.js file is.

[nodkz]

const es = require('elasticsearch');
console.log(es.Client.apis);

Of course it's better. Can you open PR?

[markbirbeck]

Ha! I might be able to, but getting a dev environment set up might be a little bit time-consuming. I'll see what I can do tomorrow.

[nodkz]

Tnx. I'm almost always online and can merge and publish new version from mobile.

[nodkz]

Travis tests cover your upcoming changes, so if you want you may send PR via online file edit 😈

[markbirbeck]

Oh...that's a good idea. Thanks.
