Error on a stored proc

Question

I am creating a stored proc to insert JSON data on the DB and I am getting an error. See my code below.

CREATE PROCEDURE InsertJson
@json NVARCHAR(MAX)
AS
BEGIN
INSERT INTO dbo.tbl_SubmissionsMaster --dbo.tbl_SubmissionsMaster([pk_DataSetId, CompleteDate, Period, OrgUnit, DataValues, SubmittedTS, ResubmittedTS])
-- Insert statements for procedure here
SELECT *
FROM OPENJSON (@json)
WITH(
DataSetId uniqueidentifier
, CompleteDate DateTime
, period datetime
, OrgUnit varchar(50)
, DataValues varchar(200)
, SubmittedTS DateTime
, ResubmittedTS DateTime
)
END
GO
