wgts qc kwik-glue sfn fails when no wgts qc samples are on the run

[alexiswl]

We get a failure because no dynamodb attribute library_id_set has been set for this instrument run id.

Can either place a 'choice' inside the trigger to determine if the item is present or initialise an empty set first

Right. Guess these are for cases like BiModal assay only run, etc.

Yes, or cttso only, this doesn't cause any issues with glue processing just that a sfn errors out when it doesn't need to.

At some point I'd like to put a slack webhook on all failed sfns in the orcabus so don't want these types of errors polluting the channel
