Cannot convert undefined or null to object

When running
node utils/nftport/genericMetas.js

i get this error:

delete jsonFile.custom_fields.dna;
^
TypeError: Cannot convert undefined or null to object

does your json files not have the dna field?

[BeatKO]

it has.

"name": "test #2",
"description": "Unique test test",
"image": "ipfs://NewUriToReplace/2.png",
"dna": "testnumber",
"edition": 2,
"date": 1641415744625,
"attributes": [

So it worked for me when i changed this line:

delete jsonFile.custom_fields.dna;
to this:
delete jsonFile.dna;

yeah, your json file is not formatted the way it's looking for. So this wouldn't be an issue with the code.
