why was "null = zoho.loginuser" statement inserted?

why was "null = zoho.loginuser" statement inserted?

Hi,

Below is my insert statement. But the line " null = zoho.loginuser" was inserted when I access the application. Moreover I'm getting error when this statement was executed. Please help me to resolve this issue

insert into SelfAssessment_Report_Form
[
    assessmentNo_SelfAssessmentReport = input.assessment_SelfAssessment_State
    category_SelfAssessmentReport = "Category1"
    noofYes_SelfAssessmentReport = 0
    noofNo_SelfAssessmentReport = 0
    noofNA_SelfAssessmentReport = 0
    noofUnanswered_SelfAssessmentReport = 0
    null = zoho.loginuser
]


Thanks & Regards,
Appadmin
