[Mani7q]

Notice: Undefined offset: 0 in /vendor/magento/module-catalog-import-export/Model/Import/Product/Type/AbstractType.php on line 537

Is there any fix for the error as above

I think there is problem with csv. Something is not found in magento what you are trying to upload.

Please make sure that csv file is formatted properly. Or you can share the file here.
