Running eslint from subdirectory

My project contains a subproject with its own .eslintrc (i.e. under ./path/to/subproject)
I'm trying to run lint but it either goes to the root project .eslintrc file or it can't find the .eslintrc file
I've tried the following configurations in package.json:

cd path/to/subproject

and:

"lint": "tsc && eslint -c .eslintrc.js ./**/*.ts --"

or

"lint": "tsc && eslint -c ./.eslintrc.js ./**/*.ts --"

Also tried in root dir:

"lint": "tsc && eslint -c path/to/subproject/.eslintrc.js ./**/*.ts --"

or

"lint": "tsc && eslint -c .eslintrc.js ./**/*.ts --"

with

npm run lint --prefix path/to/subproject/

But it keeps referring the root project .eslintrc file:

Oops! Something went wrong! :(

ESLint: 6.4.0.

ESLint couldn't find the config "configname" to extend from. Please check that the name of the config is correct.

The config "configname" was referenced from the config file in "/home/vsts/work/1/s/.eslintrc.js". <-- this is the wrong .eslintrc

The environment is Azure DevOps pipeline with Ubuntu 16.04

So it looks like eslint supports this
What I had to do is add "root": true to my eslint config file, it now looks something like this: 

module.exports = {
    "extends": [
        "configname"
    ],
    "root": true
}
