Regression in ember-eslint-parser@0.5.11

[ijlee2]

Background

When an Ember project consumes a shared eslint configuration, then running lint:js in that project results in many error messages:

Partial log from lint:js

[ember-eslint-parser] Failed to parse tsconfig: tsconfig.json Error: error TS5012: Cannot read file 'tsconfig.json': ENOENT: no such file or directory, open '/node_modules/@ijlee2-frontend-configs/eslint-config-ember/v1-app/tsconfig.json'.

I traced the bug to #131, because the errors go away when I pin ember-eslint-parser to 0.5.10.
