Their is already a username "ABCD" created successfully. Afterthat i try to create username as "ABC" this was not created and throwing an response
[body] => user abc already exists [raw_body] => user abc already exists
samething happens for userid also.
Yes I checked on that
abcd 1 testfname1testlname1 email@example.com 33DBCB07706FCA297077043CE39DC696
abce 1 testfname2testlname2 firstname.lastname@example.org 33DBCB07706FCA297077043CE39DC696
abcde 1 testfname3testlname3 email@example.com 33DBCB07706FCA297077043CE39DC696
These records are inserted without any error and now in try to insert username as abc it shows
user abc already exists [raw_body] => user abc already exists
Meanwhile I am using Rest api to create user from PHP. I forget to mention this in my question.
