@fengxsong , thank you , after set GOROOT in ENV , the bug fixed.

[camilamacedo86]

Also, note that the 1.13 is not supported yet.
You need to use 1.12+ for now.
I am closing this one since you already found the solution.

@camilamacedo86 Should the fact that GOROOT must be set, be documented somewhere (maybe user guide/getting started)?

Seems like a common problem you would run into in a clean development environment.
