Unable to set default value for a JSON env variable

[alfonmga]

I'm getting this error:

================================
 Invalid environment variables:
    POSTMARK_TEMPLATES_ID: Invalid json: "[object Object]"
    POSTMARK_TEMPLATE_VALUES: Invalid json: "[object Object]"

 Exiting with error code 1
================================

And here's my code:

// config/index.js

const envalid = require('envalid');

const { str, num, json } = envalid;

const env = envalid.cleanEnv(
  process.env,
  {
    APP_MODE: str({ default: 'dev' }),
    POSTMARK_TEMPLATES_ID: json({
      default: {
        VERIFY_EMAIL: 1,
        FORGOT_PASSWORD: 2,
        PASSWORD_RESETED: 3,
        PASSWORD_CHANGED: 4,
        EMAIL_CHANGED: 5,
      },
    }),
    POSTMARK_TEMPLATE_VALUES: json({
      default: {
        product_name: 'ACME Software v1.0',
        product_url: 'https://domain.io',
        support_url: 'https://support.domain.io',
        company_name: 'ACME Inc.',
        company_address: null,
      },
    }),
  },
  {
    dotEnvPath: '.env',
  },
);

// eslint-disable-next-line import/no-dynamic-require
const modeConfig = require(`./${env.APP_MODE}`);

module.exports = Object.freeze({
  ...env,
  ...modeConfig,
});

I'm not sure at all if I'm doing something wrong, but I believe it is a bug.

Try a JSON string for your default values (not an object). I think that should fix the error.

For example:

default: `{
  "product_name": "ACME Software v1.0",
  ...(rest of json string here)
}`

@af unfortunately, it does not work. I'm getting the same error message: Invalid json.

Do JSON.stringify around your object

@SimenB it worked, thanks!

P.S. I think maybe we should add an example to the README.md.

Sure, PR welcome 🙂
