ListTags in repository.go throws SIGSEGV panic

[paranoidd]

Hello!

First of all, thank you very much for your work!

I would like to note that I am a golang noob, and hopefully it is just me not understanding something :-)

I am trying to list all the repository tags for a given repo. Here's the code snippet I wrote for that:

func BitBucketImportRepositories() {
    c := bitbucket.NewBasicAuth(os.Getenv("BITBUCKET_USERNAME"), os.Getenv("BITBUCKET_PASSWORD"))

    opt := &bitbucket.RepositoriesOptions{
        Owner: config.Module.Import.Bitbucket.Organization,
    }

    repos, err := c.Repositories.ListForAccount(opt)

    if err != nil {
        log.Fatalf("Failed to fetch repositories from BitBucket! %+v", err)
    }

    for i := 0; i < len(repos.Items); i++ {
        if re.MatcherString(repos.Items[i].Slug, 0).Matches() {

            tagOpt := &bitbucket.RepositoryTagOptions{
                Owner: "myorgname",
                RepoSlug: repos.Items[i].Slug,
                Query: "",
                Sort: "",
                PageNum: 1,
                Pagelen: 100000,
                MaxDepth: 1,
            }

            log.Println(repos.Items[i].ListTags(tagOpt))
            break
        }
    }
}

Execution fails with the following error:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x50 pc=0x43e2081]

I am running go version go1.15 darwin/amd64

Is there anything I am doing wrong here? I'd appreciate any hints and directions.

Thank you!

Hmm, let me check. I will try that.
Thank you for your reporting. @paranoidd

[ktrysmt]

I tried a sample code and it seems to work.
So please check the code uploaded along with go-version. @paranoidd

version: go version go1.15.3 darwin/amd64
code: https://github.com/ktrysmt/go-bitbucket/blob/master/tests/list_test.go

Hey @ktrysmt, thank you for your reply!

I am sorry if this is a noob question, but in the test you've linked, I do not see ListTags method being called. The ListForAccount method from Repositories works as expected, however when calling log.Println(repos.Items[i].ListTags(tagOpt)) it gives the panic which I listed in the initial message.

I've upgraded the go version to the same as yours and still experiencing the problem :(

ListTags

Oh I see. I will do try-and-error again. Thank you. @paranoidd

[ktrysmt]

I have updated the sample code to test ListTags. Please check it. @paranoidd

This was the part I was missing, got it all running.

Thank you for your help and patience!
