The updated `next.js` dependency has a new regex match in the code for `/^\/_next\/data\//`.
This `sub_filter` creates invalid regex `/^\/overseerr/_next\/data\//`
```nginx
sub_filter '/_next' '/$app/_next';
```
It needs to be updated to substitute the correct the regex `/^\/overseerr\/_next\/data\//`
```nginx
sub_filter '\/_next' '\/$app\/_next';
sub_filter '/_next' '/$app/_next';
```
