Error while executing SSIS package which contains Script component through SQL Server Agent Job

I have written one SSIS 2012 package which is fetching records from CSV and put it into staging DB and from staging DB , using SSIS script component task, I am inserting data into Dynamics CRM. So far it is working fine when I manually execute SSIS package.

but when I run the SSIS package using SQL server agent job, I encounter below error. After seeing below error at step "Insert TLM Headers Script Component " I understand that it is failing at script component which I have used in SSIS package, but I am not sure what is the cause behind that? please advise.

Error:
