Can you provide some more context?

I'm seeing this when calling a mutation on one route, then navigating to another route and calling another mutation. I'm on version 1.0.0-alpha-11.

I'm seeing this when calling a mutation on one route, then navigating to another route and calling another mutation. I'm on version 1.0.0-alpha-11.

I also had this error, but after switching to version '^1.0.0-beta.1+1' the error disappeared

[budde377]

Upgrading to 1.0.0-beta.1+1 fixed it for me aswell.
