BoardReflectedLimitsException

can anyone tell me what is this

{
  message: 'BoardReflectedLimitsException',
  locations: [ { line: 1, column: 10 } ],
  path: [ 'duplicate_board' ],
  extensions: {
    code: 'RecordInvalidException',
    status_code: 422,
    error_data: { error_data: 'BoardReflectedLimitsException' }
  }
}

i get this when calling Boards

Looks like you are trying to duplicate a board which has connected boards configured. With the duplication you are exceeding the maximum number of connected boards for your plan.

thanks! do you know of any supporting link on the developer documentation?
