script-component

I am developing a source in SSIS VS 2017 which calls REST API using script Component and serialises JSON and provides records which I am storing in SQL Table. While designing I need add output columns which are 200+ manually and set properties like data type and length manually for each and every column which is very tedious. Can any please suggest how can I add all those columns using a program and set properties using code or may be I just create one excel and just import it and it’s done in one second. Please help brainstorm and suggest ideas VSTA is one option but I don’t know how to do it

I created SSIS packages and used the Integration Services Deployment Wizard to deploy it out to the server. I'm manually going to the Integration Services Catalog access through SQL Server 2012 and right-clicking and executing my package. However, the package keeps failing and I'm getting the following errors when I check the execution report's messages. They appear to be failing on data tasks where I have script components.
