M201 video 2.8 multikey / doc insert blocked

in the video at the very end, an example is shown of an attempt to insert a doc which errors because the insert is of doc with 2 fields that are both arrays…

is it because both fields are already designated in the db as index fields?.. and one cannot have 2 indexed array fields…

so an insert of a doc can bring in (introduce) an array field where that field has not yet been an array field in the db …except if involving a 2nd index…

Hi @James_58604,

Also suggest that you watch the entire lecture video again. This specific question was covered @ 1:00 onwards.
