Graph view not rendering

[theogravity]

• Using express middleware
• Using graphql-voyager 1.0.0-rc5
• Tried using Chrome / Safari

When I hit the graphql voyager endpoint, the sidebar loads properly, but the main view gets stuck on "Transmitting..."

In the JS console, I get blob:http://localhost:4000/427b21a8-5a9a-4f6f-8baf-463f5d906201:12 Uncaught SyntaxError: Illegal return statement

Which is buried in the bundle (under // ENSCRIPTEN_END_FUNCS)

Unsure if this matters, but the generated bundle reads rc-4 instead of 5.

@theogravity Can you reproduce it on the online demo(use Custom Schema option)?
Can you please attach result of introspection query for your API?

I will check but the only difference between rc4 and rc5 is a presence of middleware.

Hello, i can confirm the bug. It happens only with rc.5 version.

I don't agree. in this commit 96009e8 if you check yarn.lock file you will find that some dependencies were updated, one of them cause this bug

[theogravity]

I have no problems with the online demo.

I unfortunately can't paste my introspection as it would give away something we're working on at work that's secret right now.

@steplov Make sense since I forget to update online demo and it still on rc.4. So it's probably yarn.lock related bug.

can you resolve the issue?as i m also having the same issue +

   Error: Can't set headers after they are sent.

On node console.

[RomanHotsiy]

The issue was caused by upgrading viz.js to 1.8.0.
Temporarily I downgraded it back to 1.7.1 and published a new version of voyager: 1.0.0-rc.7.

Thanks all for participation!

[theogravity]

Thanks, it works!

I'm still getting this in 1.0.0-rc.7:
