When I install this helm release with flux-helm-release then it gets rendered as a different version (so instead of 0.10.1 it renderes as lastAttemptedRevision: 0.10.1+53d9c5dffd49 that then fails:

The error is:

          }

        }
      }
    }
  }
}

how can i force timoni bundle to just use that version?
