# Troubleshooting Runtime Problems

> When using Flytrap, you might in rare cases encounter problems during runtime. These are problems and solutions to possible runtime errors.

## Cannot access 'functionName' before initialization

If you havent disabled Flytrap's default function hoisting behavior in the [Flytrap config](/config/introduction), this error shouldn't happen. If it does, open an issue.

If you have disabled Flytrap's default hoisting behavior, then the above error can happen.

### Solution

You can either enable Flytrap's hoisting behavior, or move all invocations of function declarations (eg. `function foo()`) to be used after the functions are declared.

For example:

```typescript theme={null}
console.log(foo());
function foo() {}
```

Should be rewritten as:

```typescript theme={null}
function foo() {}
console.log(foo());
```
