Array of objects cannot be used as parameter: Invalid input 'n': expected

[mstimvol]

When I do the following:

  const rg = new Graph('mygraph')
  try {
    await rg.query('UNWIND $names AS name RETURN name.firstName', {
      names: [{ firstName: 'Alice' }, { firstName: 'Bob' }]
    })
  } catch (e) {
    console.error(e)
  }

I'm getting the following error:

ReplyError: errMsg: Invalid input 'n': expected ';', a statement option, a query hint, a clause or a schema command line: 1, column: 1, offset: 0 errCtx: names=[[object Object], [object Object]] UNWIND $names AS name RETURN name.f... errCtxOffset: 0

command: 'GRAPH.QUERY',
args: [
'blockchain',
'CYPHER names=[[object Object], [object Object]] UNWIND $names AS name RETURN name.firstName',
'--compact'
]
}

I guess the error occurs because [[object Object], [object Object]] is passed to the cypher query.

@mstimvol
map datatype is WIP RedisGraph/RedisGraph#1514
once it is done and map as a parameter is supported your query will be valid.
