Child table uploaded in database through csv not working

1

Hi,
I have imported child table data from csv in mysql database having appropriate “parent” field value but when I retrieve it on ui through parent object it is showing error like
“Cannot read property ‘3bac6aac909b459ec00d508f6260815c7c5150198d70f13571c2d4bd’ of undefined”
where ‘3bac6aac909b459ec00d508f6260815c7c5150198d70f13571c2d4bd’ is name of child row.

Please see image below for better understanding.

Ah this is the old version… better use data import tool to do this.
