[BUG] Can't lint go 1.22 package

[Crocmagnon]

Describe the bug
I'm trying to lint a module requiring go 1.22.
Log:

$ spancheck ./...
2024/04/22 10:44:34 [WARN] invalid start span signature "". expected regex:telemetry-type
/tmp/test/main.go:1:1: package requires newer Go version go1.22
ctrlflow: analysis skipped due to errors in package
spancheck: failed prerequisites: [email protected]/test

To Reproduce
go.mod:

module example.com/test

go 1.22.2

main.go:

package main

import "fmt"

func main() {
	fmt.Println("hello, world")
}

Expected behavior
The package should be linted properly and, in this case, not report any error.
Also there's an unexpected warning about the new start span signature.

Additional context
I installed spancheck with go1.22.2:

$ go version
go version go1.22.2 darwin/arm64
$ go install github.com/jjti/go-spancheck/cmd/spancheck@latest

Aside that's unrelated to the primary go version at hand, that WARN log line is from a small bug, just fixed that: #20

@Crocmagnon I'm unfortunately unable to reproduce, running below:

# josh @ M-FTQC4VW0R3 in ~/Desktop/main-test on git:main x [19:25:04] 
$ go version                                                  
go version go1.22.2 darwin/arm64

# josh @ M-FTQC4VW0R3 in ~/jjti/go-spancheck on git:jjti/fix-warn-start-span o [19:15:06] 
$ go install github.com/jjti/go-spancheck/cmd/spancheck@latest
go: downloading github.com/jjti/go-spancheck v0.6.1

# josh @ M-FTQC4VW0R3 in ~/Desktop/main-test on git:main x [19:20:53] 
$ cat go.mod 
module github.com/jjti/test

go 1.22.2

# josh @ M-FTQC4VW0R3 in ~/Desktop/main-test on git:main x [19:20:55] 
$ ls
go.mod  main.go

# josh @ M-FTQC4VW0R3 in ~/Desktop/main-test on git:main x [19:20:56] 
$ cat main.go 
package main

import "fmt"

func main() {
        fmt.Println("hello, world")
}

# josh @ M-FTQC4VW0R3 in ~/Desktop/main-test on git:main x [19:20:58] 
$ spancheck ./...

I tried cloning the repo and building it with my local toolchain (go 1.21), I'm getting the same error as reported.
I then updated the toolchain to go1.22.2 with go get toolchain@latest and after building I'm still getting the same error.
However, if I instead update the go.mod to go1.22.2 (go get go@latest) and build, I'm not getting any error.

Finally, I tried to install go-spancheck with the go1.22 toolchain after cleaning the modcache, but I'm getting the same error as reported.

Tested on master, commit 1288474

@Crocmagnon I'm sorry to say I could never repro this issue. But I just upgraded the go version to 1.22.1 (in line with testifylint). Please let me know if you see the issue still after upgrading: 926dd06
