Any idea how to identify what is causing : warn Error persisting state

[cameronbraid]

warn Error persisting state: function plugin({
  beginMarker,
  endMarker,
  pattyName = 'patty',
  onlyRunWithMarker = false,
  insertBef...<omitted>...
} could not be cloned.

The error look like this :

Error: function plugin({
  beginMarker,
  endMarker,
  pattyName = 'patty',
  onlyRunWithMarker = false,
  insertBef...<omitted>...
} could not be cloned.

    at build (/media/workspace/drivenow-octane/node_modules/gatsby/src/commands/build.ts:188:12)

the side effect of this is that my .cache folder is wiped each build (since old plugin hash is not saved)
