Can't override route using ForestRequest in TypeScript

[mauricius]

Hello!

I'm trying to override a route by using the snippet provided here https://docs.forestadmin.com/woodshop/how-tos/translate-your-project-into-typescript/v8/migrate-sequelize-files#override-your-routes, however I can't get around some typing issues with ForestRequest that conflict with Express' Request.

This is my code:

router.post('/actions/close', permissionMiddlewareCreator.smartAction(), async (req: ForestRequest, res: Response) => {
    ...
});

Expected behavior

Compile successfully.

Actual behavior

Compilation error.

For future reference to those who might find this issue, I had this issue too, the workaround was to cast inside the function.

router.post('/actions/close', permissionMiddlewareCreator.smartAction(), async (req: Request, res: Response) => {
    const forestRequest = req as ForestRequest;
});
