Git plugin ignores onInvalidSyntax when exporting invalid flows (plugin v1.2.1)

[csiiutpro]

Describe the issue

Description

When trying to sync a Kestra tenant to Git using the io.kestra.plugin.git.TenantSync task, the export fails if there are flows with invalid syntax, even when onInvalidSyntax is explicitly set to something other than FAIL (e.g. WARN or SKIP).

This prevents us from saving the full state of our Kestra instance to Git.

Context

We have a few legacy flows that are currently invalid because they rely on plugins incompatible with our current Java version. These flows are intentionally kept as-is and are expected to become valid again later without requiring any changes.

Our goal is to back up the tenant (including these flows) to Git until they can be reused.

Expected behavior

When onInvalidSyntax is set to WARN (or SKIP), the tenant sync should continue and simply warn or skip invalid flows, without failing the entire TenantSync task.

Actual behavior

The TenantSync task fails during flow export, ignoring the onInvalidSyntax setting.

Steps to reproduce

Have at least one invalid flow stored in Kestra

My case : a flow using a non-existent or incompatible plugin type.

Configure a TenantSync task with:

onInvalidSyntax set to WARN (or any value other than FAIL)

Run the TenantSync task.

The task fails instead of warning or skipping the invalid flow.

Configuration example

  - id: sync_tenant
    type: io.kestra.plugin.git.TenantSync
    url: https://my_local_git.com/kestra_sync
    kestraUrl: "http://x.x.x.x:8080/kestra"
    branch: test
    whenMissingInSource: KEEP
    sourceOfTruth: KESTRA

    onInvalidSyntax: WARN

    auth:
      password: "{{ secret('SERVICE_INTERNAL_KESTRA_API_PASSWORD') }}"
      username: "kestra@kestra.kestra"
    password: "{{ secret('SERVICE_KESTRA_GITLAB_TOKEN') }}"
    username: "svc_kestra"
