How To Solve Uncaught Error: Invariant Violation: Objects are not valid as a React child Error ?

Solution 1: Use toString

Here what you are trying is Object You’ll need to either reference a property of the object that is a string value or converts the object to a string representation that is desirable. One option might be JSON.stringify if you actually want to see the contents of the Object. Just Use toString().

{this.props.task.userId.toString()}

Solution 2: Use BreadcrumbItem

Here Object in your JSX code that is expected to be a string value. Something Like That.

return (
    <BreadcrumbItem href={routeString}>
        {breadcrumbElement}
    </BreadcrumbItem>
)

Solution 3: Use single braces

Here I just got the same error but due to a different mistake: I used double braces like:

{{userId}}

to insert the value of userId instead of the correct:

{userId}

which the compiler presumably turned into {{userId: userId}}, i.e. trying to insert an Object as a React child.
