[ BUG ] panic: runtime error: index out of range [1] with length 1

[sOblivionsCall]

I have a CircleCi pipeline that triggers on commit to the main branch. CR is ran using docker with the latest tag:

version: 2
jobs:
  package-upload-index:
    docker:
      - image: quay.io/helmpack/chart-releaser
    steps:
      - checkout
      - run:
          name: package
          command: |
            charts=$(find . -maxdepth 1 -type d \( ! -name .git ! -name .deploy ! -name .circleci ! -name . \) -print)
            for chart in $charts
            do
              cr package $chart
            done
      - run:
          name: upload
          command: cr upload -o soblivionscall -r charts
      - run:
          name: index
          command: |
            apk add git
            cr index -i ./index.yaml -o soblivionscall -c https://soblivionscall.github.io/charts/ -r charts --push

workflows:
  version: 2
  release:
    jobs:
      - package-upload-index:
          filters:
            tags:
              ignore: /.*/
            branches:
              only: main

On the index step i am seeing:

#!/bin/sh -eo pipefail
apk add git
cr index -i ./index.yaml -o soblivionscall -c https://soblivionscall.github.io/charts/ -r charts --push

Exited with code exit status 2

CircleCI received exit code 2

Obviously it's an issue with an out of bounds index but i don't know what index it is referring to. This pipeline has ran flawlessly for months without any changes so i'm fairly certain it's not something i did. Can anyone provide some insight as to what might be going on?

[sOblivionsCall]

Can confirm this is a bug in the latest tag of the docker container and most likely the v1.2.1 tag as they appear to have been uploaded at the same time.

https://quay.io/repository/helmpack/chart-releaser?tab=tags

My issue was resolved by using the 1.2.0 tag. Will leave this issue open for tracking and debugging by the devs but i am no longer blocked.

thanks, @sOblivionsCall for the report, I don't have time this week to look over this, but I can try in my weekend, I need to set up an env for that.
meanwhile if you want to submit a PR we thank you in advance

[cpanato]

hello @sOblivionsCall sorry for the delay

I was able to reproduce this issue only when my remote was configured as ssh like (git@github.com:cpanato/charts.git) then I got the exact error, when I convert that to be https (https://github.com/cpanato/charts.git) it worked

can you check how your remote looks like? for ssh it will not work, the chart-releaser expect a HTTPS remote + token

[pratikbin]

Ran into same issue in my CI so add little workaround which will set https for only cr index step if repo remote is SSH and then undo it

    [[ $(git config --get remote.origin.url) == *"git@github.com"* ]] && \
    SSH_REPO=true && \
    PROJECT_USERNAME=$(git config --get remote.origin.url | sed 's/git\@github\.com\:\|\.git\|https\:\/\/github\.com\///g' | awk -F\/ '{printf $1}') && \
    PROJECT_REPONAME=$(git config --get remote.origin.url | sed 's/git\@github\.com\:\|\.git\|https\:\/\/github\.com\///g' | awk -F\/ '{printf $2}')

    [[ ${SSH_REPO} == *"true"* ]] && \
      git remote set-url origin https://github.com/${PROJECT_USERNAME}/${PROJECT_REPONAME}
    cr index --push
    [[ ${SSH_REPO} == *"true"* ]] && \
      git remote set-url origin git@github.com:${PROJECT_USERNAME}/${PROJECT_REPONAME}.git

[cpanato]

the chart release expect the remote to be HTTPS and not SSH

[pratikbin]

This will set https for only cr index step if repo remote is SSH and then won't do it

[RobbieMcKinstry]

Experiencing the same bug.
The problem seems to be these lines here assume the origin uses https:// and not git://. To reproduce, set the origin to use something like git@github.com:MyOrganization/MyRepository and run cr index with the other parameters set as usual.
Possible Workaround (not confirmed): Edit your remote to use HTTPS instead.

Hit this as well. Needed to read source code to find out what the problem is....
