Cannot push to codecommit using bitbucket pipelines

Hi All,

I am trying to push the repository to codecommit through bitbucket pipeline. It was working fine .

Now, I am facing an error. the error looks like.

remote: processing ... remote: Unknown commit d7e9a3fbcef21e0ac40ba142f2f528cd0d3db1b1error: unpack failed: Unknown commit d7e9a3fbcef21e0ac40ba142f2f528cd0d3db1b1To ssh://git-codecommit.us-west-2.amazonaws.com/<repodetails> [remote rejected] Development -> Development (unpacker error)error: failed to push some refs to 'ssh://git-codecommit.us-west-2.amazonaws.com/<repodetails>'

this prevents from pushing to remote AWS codecommit.

Any idea how to solve this. I did check the mentioned commit and its assigned perfectly fine with the author details.

@Vimal krishnamoorthy do you mind sharing a snippet from you bitbucket-pipelines.yml file? I haven't used CodeCommit before, however something to consider is that in pipelines, we perform a shallow clone of your repository (to a depth of 50, see the log output from Build Setup).

Its possible that you are now trying to push to CodeCommit without having the full commit history.

Are you able to push the same commit from your local machine? I would also suggest trying to test locally by cloning your repository with a depth of 50 (git clone --depth 50 <your repo>), then try to push to CodeCommit, and see if depth causes it to break.

Vimal krishnamoorthy

Yes , You where right. We moved to bitbucket from github recently and this was the reason for not having a complete commit history. And CodeCommit will throw an error in such cases.

I started everything fresh from scratch in bitbucket by creating a new fresh repository and IT WORKED. It was better then wasting time trouble shooting the issue.

THANKS FOR THE HELP. BTW THIS WAS MY yml file.

- step: name: Pushing Repository to AWS codecommit

deployment: staging

script:

- echo $CodeCommitKey > ~/.ssh/id_rsa.tmp

- base64 -d ~/.ssh/id_rsa.tmp > ~/.ssh/id_rsa

- chmod 400 ~/.ssh/id_rsa

- echo $CodeCommitConfig > ~/.ssh/config.tmp

- base64 -d ~/.ssh/config.tmp > ~/.ssh/config

- set +e

- ssh -o StrictHostKeyChecking=no $CodeCommitHost

- set -e

- git remote add application ssh://$CodeCommitRepo

- git push application $BITBUCKET_BRANCH

@Vimal krishnamoorthy if you don't mind me asking, what method did you use to migrate over from github? I'm curious to find out how this could have caused issues in this case?

James Hulse

@Graham Gatus for anyone else coming across this issue, I ran into the same thing when trying to push directly from a Bitbucket pipeline to a brand new CodeCommit repository.

The issue *does* seem to be the lack of history. To solve the issue I first pushed from my local machine, then subsequent pushes from the Bitbucket pipeline worked.

Hi @Vimal krishnamoorthy ,

Use ssh keys you'll need to setup both the sender (pipelines) and the receiver (aws codecommit)

To set up ssh keys for use in pipelines you can consult our documentation here https://confluence.atlassian.com/bitbucket/use-ssh-keys-in-bitbucket-pipelines-847452940.html

To set up ssh keys for use in aws codecommit you can consult the documentation here https://docs.aws.amazon.com/codecommit/latest/userguide/setting-up-ssh-unixes.html

If you have any other questions let me know.

Cheers,

Abhishek
