you need to consider the string may contain multiple commas in the "Name" value, so the "split" will be affected by this
"Type: Process Model, Name: [en_GB=, en_US=PM Test, es=], Id:5946, ...."
agreed, for this I would just go ahead and use the extract() function.
index(extract( local!details, "Id:", ", UUID" ), 1, null())
