This error message usually occurs when there is a problem with the type of data being passed to an output stream in C++.
Here's an example:
```
#include <iostream>
int main() {
int x = 10;
std::cout << "The value of x is: " << x << std::endl;
return 0;
}
```
In this example, we are trying to output the value of the integer variable `x` to the console using the `std::cout` object. However, if we try to output an object of a type that does not have a defined output operator, we will get an error message similar to the one you mentioned.
To resolve this error, we need to make sure that the data type being passed to the output stream is compatible with the stream's output operator. In some cases, we may need to define our own output operator for a custom data type.
