# Try-Catch
You can add any building block — or a sequence of multiple building blocks — after the **Start Try-Catch** block. All of these blocks will be part of the Try-Catch scope.
If an error happens inside this scope, the TaskBot will immediately continue along the **On Catch Error** path, where you can define how to handle the error.
After either the success path or the error path is completed, the TaskBot will continue along the **After Try-Catch** path.
### Examples
1. If any error (no differentiation) occurs inside a loop, break the loop and continue after the loop.
2. Different try-catch scopes with different error handling strategies for different building blocks.
3. Record the error message and handle the error differently depending on the error.
{% hint style="warning" %}
If the TaskBot can’t start its run at all, the error won’t be caught — even if you wrap the entire workflow in a try-catch block. This usually happens for one of two reasons:
* Outdated agent version
* Invalid TaskBot set-up
{% endhint %}
