Getting 1007 error code

[Anonymous]

Hi,

I am trying to create leads of 300 in marketo using Rest APIs with "createOnly" option. "Email" is the lookup criteria.

There are some leads having Null Email values.

For some leads we are getting error code as 1007 as response. But according to the documentation this error code should be returned when we try to update a record and if there are multiple matches with the given look up criteria.

So why am I getting this error code in case of "createOnly" request.
