fix(sdk/go): Fallback when tenantID is zero UUID

[gregfurman]

Description

This PR checks if the supplied Tenant ID is either empty "" or the zero uuid.UUID value 00000000-0000-0000-0000-000000000000 -- where the only the former was being checked which causing tenant IDs not to be extracted from supplied tokens with v1.NewHatchetClient(...) calls.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)

What's Changed

• When a tenant ID is the zero value for a uuid.UUID, this triggers a fallback to extract from the passed in token.

Testing

Using the below client.yaml, run the go script both with and without the change.

token: "<token>"
log:
  level: debug
tls:
  base:
    tlsStrategy: none

package main

import (
	"fmt"
	"os"

	clientloader "github.com/hatchet-dev/hatchet/pkg/client/loader"
	v1 "github.com/hatchet-dev/hatchet/pkg/v1"
)

func main() {
	configBytes, err := os.ReadFile("client.yaml")
	if err != nil {
		panic(err)
	}

	cf, err := clientloader.LoadClientConfigFile(configBytes)
	if err != nil {
		panic(err)
	}

	client, err := v1.NewHatchetClient(v1.Config{
		Token: cf.Token,
		TLS: &v1.TLSConfig{
			Base:          &cf.TLS.Base,
			TLSServerName: cf.TLS.TLSServerName,
		},
	})
	if err != nil {
		panic(err)
	}

	fmt.Printf("TenantID: %s\n", client.V0().TenantId())
}

You'll see HEAD of main return:

TenantID: 00000000-0000-0000-0000-000000000000

with these changes added:

TenantID: 707d0855-80ab-4e1f-a156-f1c4546cbf52 # or whatever tenant ID was used in your token generation
