Also happens if you click "re-run options" and "run now".
But probably the root issue is I updated the pipeline template into a broken one.

=== In more detail ===
--> I tried to coerce the ordering of the jobs to serial by adding to the second job
input:{
output_of:Create Two Files
},

which arv edit accepted, but trying to run this template made everything else sad.

===Oh, more detail! the issue was my runtime_constraints was inside my script_parameters

incorrect: script_parameters:{ runtime_constraints:{}}
correct: script_parameters:{}, runtime_constraints:{}
