Which issue does this PR close?
Closes #10791.
Rationale for this change
When the
argsare empty, they panic at display_name, due to "index out of bounds".datafusion/datafusion/functions-array/src/extract.rs
Lines 253 to 256 in ece7ae5
The fix is to use an empty string as the arg name if it is out of bounds, allow
display_nameto pass through, and subsequently generating an error by checking the signature.What changes are included in this PR?
