I know that some field is > getting a null where there is a non-nullable string but in order to find out > which one it is I either have to check all possible non-null string fields > for null values, look at which columns are changed recently and guess and > check, or throw a debugger in and dive down the stack. So far, the last has > been the fastest for me. > Ideally, I would like the error message to tell me which field has the null > value so I can fix the problem with high confidence and without the use of a > debugger. -- This message was sent by Atlassian Jira (v8.20.10#820010)
