SSIS Connection not found in package

Question

I\'m kind of new to SSIS programming, and I\'m having some problems deploying an SSIS package.

This package runs correctly on my PC, does everything it needs to do ..

Answer 1

I had the same problem.

I use project level connection managers and my packages run correctly in SSDT but when I deployed them and execute them through a job with sql server agent, I get "Connection not found" errors.

So I deploy the project and then the problem was solved, when you use project level connection managers but just deploy a single package from that project, and you call package through sql server agent, it could not recognize your connection managers so you should determine package level connection managers or you should first deploy your project.
