Actually, I solved generic json reader url issue but I didnt solve generic json writer;

because it creates wrong column of diffrent url, it gets old columns

Hi @ikubra800​ what columns are you expecting to get in the Generic JSON writer? Would you be able to share a screenshot of the columns you get from the JSON Writer? If these are the expected columns, you can set the Attribute Definition to Manual in the Generic JSON writer and then set the column names and types manually.

Thanks for your response @danminneyatsaf​ 

when ı send to reader diffren json url, I expect to see the diffrent column parameter in this url. Like this;

For First json data url and it s works;

For Second json url and columns does not change ;

Have you tried setting the Attribute Definition to Dynamic on the Writer feature type? If you can provide your workspace, it might help us play around with what you have so far.
