my context variable is null in the tMysqlInput query

Anonymous — Thu, 15 Mar 2018 14:10:12 GMT

Hello!

I have a problem with my job when I want to make a query with 2 context variables. I attached photos with my job and my components and when I run the job, it's giving me this error:

Exception in component tMysqlInput_1 (facebook_amazon_us)
java.lang.NullPointerException
at mava.facebook_amazon_us_0_1.facebook_amazon_us.tWaitForFile_1Process(facebook_amazon_us.java:2058)
at mava.facebook_amazon_us_0_1.facebook_amazon_us.tMysqlConnection_1Process(facebook_amazon_us.java:798)
at mava.facebook_amazon_us_0_1.facebook_amazon_us.runJobInTOS(facebook_amazon_us.java:5363)
at mava.facebook_amazon_us_0_1.facebook_amazon_us.main(facebook_amazon_us.java:5085)

What I want to do in this job: I have a csv file with multiple columns. The first one is called Reporting_Starts. I want to get the first registration from that column and put it in the query for a select like: SELECT * FROM my_table WHERE MONTH(my_table.Reporting_Starts)='"+context.month+"'. I cannot get why my tJava_4 sees the variables and tMysqlInput don't.

In my tJava_4 I have the following code:

System.out.println(context.month);

Please let me know if you need any additional information about the job.

Thanks!

I think this because of the link between the components. could you please try removing iterate link from tInputFileDelimited_1 and connect javarow1 to java4 with onComponentOK link.
