helmfile: JsonPatches doesnt work

linebreaks only for readability

Error: accumulating resources: accumulateFile "accumulating resources from 'helmx.1.rendered/cluster-crd/templates/01-prometheus-operator.yaml':

this is the helmfile piece that produces the error:

- name: prometheus-operator
  chart: localFolder
  jsonPatches:
  - target:
      version: v1
      kind: ServiceAccount
      name: prometheus-operator
    patch:
    - op: replace
      path: /metadata/namespace
      value: monitoring

the file that its rendering is pretty much this file. Any pointers?
