When you receive the error message “received nan for the ‘children’ attribute, if this is expected, cast the value to a string,” it generally means that there is a problem with the data being passed to the ‘children’ attribute in your HTML code. The error message “nan” stands for “not a number”, indicating that the value provided is not a valid number.
To resolve this error, you need to ensure that the value passed to the ‘children’ attribute is a valid number or a string representation of a number. If the actual value you are trying to pass is not a number but you expect it to be accepted, you can simply convert it to a string before using it in the ‘children’ attribute.
Here is an example of how you can handle this error:
// Incorrect usage, where the value is not a number
<div children={NaN}>Content</div>
// Corrected usage, by casting the value to a string
<div children={String(NaN)}>Content</div>
