A component that is not sub process start cannot have any link OnComponentOk / OnComponentError in input

[VictorFaure]

Hello,
I'm currently working with a job that either calls to a DB using tDBInput with JDBC connection OR requesting an API.

The output schema is not known so it is one column that is of type Dynamic.

My goal is to unite (somehow) the output from DB and API to write to a file later, with tUnite component I get the title message : "A component that is not sub process start cannot have any link OnComponentOk / OnComponentError in input".

My question is either how to tackle the current issue, or how to join both output that should never output at the same time, meaning either the DB will output something or the API.

Respectfully,

Victor Faure
