Hi, there.
I’m trying the following query in Apollo Graphql Studio while checking the tutorial.

query GetLaunches {
  launches {
    id
    mission {
      name
    }
  }
}

However, It then indicates the error message, “Cannot read property ‘launchAPI’ of undefined”, on the right side of the screen when I click “Get launch”.

I want to display the server response based on the query, “GetLaunches”. What and how should I fix to display the data?

In addition, in order to execute the query, I have already done and uploaded the programming based on the tutorial on GitHub.

Thank you.

Same story, fighting this for a month!
Do you find the solution?
Thanks:)

Hi!
I have yet to find the solution.
So I’m trying Odyssey, instead of the tutorial.
In Odyssey, you might be able to check the apollo-graphql’s action.
Thank you.

Thank you!
For the last month I went through another video-tutorial but got this error over and over again. I read all the forums I could find, but none of the solutions helped.

Finally, I found the solution myself. I’m a newbie, so I didn’t understand how it works, also I didn’t find anything about it in the Apollo documentation. I know we can have completely different situations, but adding the line “_root: undefined” solves the problem for me. Without it, it’s an error.

Also, in my case it must be passed in second place, after the line “parent: Parent”, otherwise there will be an error with searching in MongoDB lately.

I guess it’s not a robust solution, just a kludge, but i get the same result, as in tutorial. Also it seems strange to me why in the tutorial everything worked without it (also i checked versions in package.json several times and made them identically)
