When adding a history object, gen does not know how to handle it:

no gen found: {
  inputs: [
    {
      name: 'history_ddd4c7c47a6847138c6f1c715f23da0d_name',

      max: 20000,
      initialValue: 0,
      defaultValue: 0,
      waapi: null,
      isWorklet: false,
      memory: [Object]
    }
  ],
  memory: { value: { length: 1, idx: null } },
  recorder: null,
  in: [Function: _in] { _name: '_in' },       
  out: {
    gen: [Function: gen],
    memory: { value: [Object] },
    name: 'historyddd4c7c47a6847138c6f1c715f23da0d0_out'
  },

Given a doc with a history op patched between two ops to allow for a feedback connection:
