Based on the error log, the key presented to bitbucket.org to authenticate is not authorised to clone.

```
debug1: Offering public key: /home/build/.ssh/id_rsa RSA SHA256:WZEhZExWuRbomATkll0DsmnE3gBouiXd9tKH8mpakuA agent
debug1: Server accepts key: /home/build/.ssh/id_rsa RSA SHA256:WZEhZExWuRbomATkll0DsmnE3gBouiXd9tKH8mpakuA agent
```

Locate the pub key for /home/build/.ssh/id_rsa and identify if it has been added to the account as per our KB [here.](https://support.atlassian.com/bitbucket-cloud/docs/set-up-personal-ssh-keys-on-macos/#Provide-Bitbucket-Cloud-with-your-public-key)

Let me know how it goes
