console appears
Cannot find a differ supporting object "[object Object]" of type "object". NgFor only supports binding to Iterables such as Arrays.
I probably know because of the array object structure,
but the screen works normally, so do I still need to pay attention to it?
because of the large amount of data, I am worried that data preprocessing will affect the performance
if you want to deal with it, does anyone have the experience of dealing with this error? it seems that you can"t be fooled by changing it into a class array?
