". I made sure to run a frequency sweep before setting up the parameter sweep to have the results from the frequency sweep available in the objects tree and can actually choose results form the frequency sweep when setting up the results of the parameter sweep".

Maybe this is the problem: when you have result in the object tree, you must have run the simulation to have modes there. However, when you do the parameter sweep, the modes are gone. this is why it cannot find the result.

The first option is better with script.
