Taking a closer look at your endpoint... are you sure that's a Mailchimp URL? I'm trying to think what else this could be... did you have this working before and it just failed? Or did you just install this?

I usually recommend removing as much as possible from your environment and slowly adding stuff back in to see if there is a conflict. For example, try using the basic starter from Gatsby with your endpoint, see if you can get that working. If not, that means there is a problem with your endpoint. But if it does work then likely there is a conflict with another plugin.

@isaacsultan and also use the method defined in the docs i.e. addToMailchimp instead of camel case.

The same issue observed in my case, which gets resolved after restarting node (npm start). I was able to add a couple of emails within the last couple of days and then I've run it today and had the same issue:

Uncaught (in promise) ReferenceError: GATSBY_PLUGIN_MAILCHIMP_ADDRESS is not defined at addToMailchimp

which points to this piece of code:

    // eslint-disable-next-line no-undef
    var endpoint = __GATSBY_PLUGIN_MAILCHIMP_ADDRESS__;

@isaacsultan and also use the method defined in the docs i.e. addToMailchimp instead of camel case.

it's okay, addToMailchimp has a default export

@benjaminhoffman Mailchimp URL looks correct

Aug 27 '19 07:08 Okelm

Having the same issue. I have also tried passing my MC endpoint URL in as a param to addToMailChimp but the same ReferenceError: GATSBY_PLUGIN_MAILCHIMP_ADDRESS is not defined is still happening. Endpoint is ok because I send a POST to the same endpoint using Postman and got a 200 back. Could be an issue with conflicting es-lint settings? (shot in the dark, no exp with es-lint)

@nh273 Any luck with this? I'm having the same issue all the sudden.

May 01 '20 16:05 scarsam

this is so weird. does anyone here have repro steps i can do? no updates have been made to the plugin so 🤷‍♂️

I'm going to try what you suggested and start removing plugins to see if there is a plugin conflict happening, I'll circle back here later today.

I had a silly mistake in my gatsby-config.js causing this error. Two of my plugins were defined in the same object.. 🤦

plugins: [{
  resolve: 'gatsby-plugin-mailchimp',
  options: {
    endpoint: 'xxxxx',
  },
  resolve: `gatsby-source-stripe`,
  options: {
    objects: ['Sku', 'Product'],
    secretKey: xxxx,
    downloadFiles: true,
  },
}]

The Stripe and Mailchimp plugin was defined in the same object causing this issue.

plugins: [{
  resolve: 'gatsby-plugin-mailchimp',
  options: {
    endpoint: 'xxxxx',
  },
},
{
  resolve: `gatsby-source-stripe`,
  options: {
    objects: ['Sku', 'Product'],
    secretKey: xxxx,
    downloadFiles: true,
  },
}]

No worries we've all been there, including me 🤦. I have just checked what's happening on my site and I can see it's still working, but it takes a super long time for the state to change and display the message (anyone else have this). Also sometimes get a cors warning in my console. I thought I'd taken care of that through micro-cors package but apparently not.

I had the same problem but I only had to restart the gatsby server and it worked again

May 07 '20 09:05 GenisDiaz

Looks like this may be solved? Would love to close it but if anyone is still experiencing issues, I am happy to keep it open.

May 25 '20 02:05 benjaminhoffman

I have the same issue, when I try to import Mailchimp, I have this error, "Could not find a declaration file for module 'gatsby-plugin-mailchimp'. 'implicitly has an 'any' type. Try npm install @types/gatsby-plugin-mailchimp if it exists or add a new declaration (.d.ts) file containing declare module 'gatsby-plugin-mailchimp';ts(7016)"

my gatsby verson is 2.24.2, how can I get pass this error.

Aug 22 '20 09:08 MuhammadSalah99

I'm facing the same issue ,it keep saying https is not defined. Even after restart and installing npm install gatsby-plugin-mailchimp, i'm receiving the same message.

Mar 18 '22 04:03 muntiMedia

I had this issue and it was down to the formatting of my gatsby-config.js.

Weirdly, the previous plugin in the file didn't have a comma after a }. It was the last { in the list but putting the comma in made the the Mailchimp plugin suddenly start seeing the configured endpoint.
