The Partners GraphQL API responded unsuccessfully with errors

I am developing an extension and recently when I running the when I running the shopify app dev command, I receieved the error below

The Partners GraphQL API responded unsuccessfully with errors: 
[ 
 { 
 "message": "Unexpected system error", 
 "extensions": { 
 "code": "500" 
 } 
 } 
]

This just happened recently, do anyone faced this issue? or how to solve this?

Hi! I’m having same issue since a few hours ago…

GraphQLClientError:
    The Partners GraphQL API responded unsuccessfully with errors:

    [
      {
        "message": "Unexpected system error",
        "extensions": {
          "code": "500"
        }
      }
    ]

Looks like something is wrong on Shopify server side. I would say that is not something specifically related to extensions since I don’t have anyone in my app.

@JackL no really sure if it’s just a coincidence or if they fixed now.

But after run

yarn shopify app dev --reset

It started working again.

Ya seems Shopify’s side have did the fix, thanks for reply too!
