I'm trying to make a post request for a storefront access token and I got this error. From looking around in the posts I see that my access token may be one of 3 different conditions, but I don't know which of them it could be. I was following the authentication tutorial in "Build a shopify app with Node and React". Could anyone let me know what the problem with my access token is?
The access token was generated today on 10/10/2020.
The access token is within your app. So locate the app screen in your store's dashboard and click on the link, there you should find your key/ token. Good luck, and let me know how you get on!
I've just had another read of your initial question and realised that you are in fact making a request for the token.
The solution in this case:
..was to omit the access_token parameter when making the request. Have you done that already?
