Error when running `yarn generate-adaptors`

Description
I was getting the error below 👇🏽, when running yarn generate-adaptors.

ERROR] Sidebars file at "/Users/openfn/Workspace/docs/sidebars-adaptors.js" failed to be loaded.
[ERROR] Loading of version failed for version current

[ERROR] Error [ValidationError]: {

    }
  ]
}

I traced the root cause of the error to https://github.com/OpenFn/docs/blob/main/sidebars-adaptors.js#L89-L91

  const extras = overviews
    .filter(id => !adaptors.map(a => `${a.name}`).includes(id))
    .map(id => ({ type: 'doc', id, label: id }));

which was happening because id was '' for one of the record. I fixed it by checking if id && !adaptors.map(a => ${a.name}).includes(id) But i am not sure if this is the proper fix because we need to know why the id value is ''

Start by running yarn generate-adaptors and inspect sidebars-adaptors.js around lines 89-91. Trace which overview record produces an empty id and determine whether the source data or sidebar generation is responsible. Done means the underlying cause is addressed and the command completes without the Docusaurus sidebar validation error.
