The error "Assignment to constant variable" in Node.js occurs when you try to modify a value assigned to a constant variable. In JavaScript, declaring a variable with `const` makes it read-only and its value cannot be changed once it is assigned.
Here is an example that shows this error:
```javascript
const myVariable = 10;
myVariable = 20; // Error: Assignment to constant variable
```
To fix this error, you can either change the variable declaration to `let` or `var` if you need to modify its value later, or you can restructure your code to work with the constant variable as intended.
