Attempt to de-reference a null object about custommetadataloader

[keerthanshetty25]

Hi
Even i had faced the similar issue using this tool and i feel there is issue with controller coding of the package. but i have done workaround which will work. below are the steps you have to do to upload the content

1. once you create .csv file open this file in notepad++ and and replace comma(,) with semicolon(;) for all
   2.Save the file as .csv itself and now upload this file in custom meta data loader.

it has worked for me i hope it will work for you also

Thanks

Happened to me as well.
@keerthanshetty25 workaround worked like a charm.

I'm having the exact same issue. Probably going to be faster to manually create the records at this point. Bummer. Disappointing first impression of what could be a really cool tool!

I personally found that the fix for this was to update MetadataUtil lines 65-72 with this:

        Set<String> fieldNameSet = new Set<String>();  
        for (String fieldNames :header) {
            if (String.isBlank(fieldNames)) {
                continue;
            }

            fieldNameSet.addAll(fieldNames.split(';'));
        }

and lines 87-95 with this:

            List<String> fieldValueList = new List<String>();

            for (String singleRowFieldValues :singleRowOfValues) {
                if (String.isBlank(singleRowFieldValues)) {
                    continue;
                }
            
                fieldValueList.addAll(singleRowFieldValues.split(';'));
            }

I would submit a pull request for this, but not sure if it's the perfect fix for everyone or not. I found that since the sets were being assigned each time in the loop rather than just adding to the set, it was overwriting the previous column's data
