k8s.io/klog/v2/klog logger types error

What is the question:

I'm having the following output trying to exec the readme.md sample

➜  engine git:(engine-sls-workflow) ✗ go version

This is the code I'm trying to implement:

package main

import (
    "github.com/serverlessworkflow/sdk-go/v2/model"
    "github.com/serverlessworkflow/sdk-go/v2/parser"
)

func ParseWorkflow(filePath string) (*model.Workflow, error) {
    workflow, err := parser.FromFile(filePath)
    if err != nil {
        return nil, err
    } 
    return workflow, nil
} 

func main() {
      path := "./example/sample.json"
      w, err := ParseWorkflow(path)
      if err != nil {
            log.Fatal(err)
      }

      fmt.Print(w)
}

Any ideas?

Sorry, @andresmijares. This one slipped from my inbox. I was on vacation, returning today. I'll take a look later this week.

[andresmijares]

thank you!!

[ricardozanini]

@andresmijares I know that's silly, but have you tried running on Go 1.14?

[andresmijares]

@ricardozanini i haven't! I will test it this weekend! ty for the suggestion

[bryanl]

For those finding this through a Google search, try updating your klog dependency. k8s.io/klog/v2 v2.70.1 works.

[ricardozanini]

Thanks, @bryanl. I've opened an issue to track this down. I'll upgrade our dependencies.
