robotframework: Dictionary has no key error - list

Question

When I run the test DICT-WITH-LISTS, I get an error that says dictionary has no key. But as you can see I did print the key and the key whose value is meant to be a list seems to be there.
Not sure what I am doing wrong and why my key is showing up differently in the error message.
I would greatly appreciate any help in resolving this issue

Change the way you are referencing the key here, from:
Run Keyword Append To List &{object2resMappingList}[${totalObjList}[${index}]] ${resName2resObjMappingList['${lane2resNameMappingList[${index}]['resName']}']}
to:
Run Keyword Append To List ${object2resMappingList['${totalObjList}[${index}]']} ${resName2resObjMappingList['${lane2resNameMappingList[${index}]['resName']}']}
