Warning: Do not call Hooks inside useEffect(...), useMemo(...), or other built-in Hooks

Hi,
sorry, I'm still learing React and the ropes of firecms :)

I'm getting this warning when using an extraAction.
Warning: Do not call Hooks inside useEffect(...), useMemo(...), or other built-in Hooks. You can only call Hooks at the top level of your React function. For more information, see https://reactjs.org/link/rules-of-hooks

I have this simple function:

import React from "react";
import {
    SelectionController,
    useStorageSource
} from "@camberi/firecms";
import { Button } from "@mui/material";

export function PrintDecksAction({ selectionController }: {
  selectionController: SelectionController
}) {
  let storage = useStorageSource();
  const onClick = (event: React.MouseEvent) => {
      console.log (selectionController);

  };
  
  return (
      <Button onClick={onClick} color="primary">
          pdf of selection
      </Button>
  );
}

which I import and apply as an extraAction:

import { PrintDecksAction } from "./collections/decks";


buildCollection({
                path:"decks",
                exportable: false,
                schema:DecksSchema.schema(),
                extraActions:PrintDecksAction,
                name: "Decks",
                permissions: ({entity, path, user, authController, context }) => {
                  return ({
                      read: true,
                      create: isadmin,
                      update: isadmin,
                      delete: isadmin
                  });
              }
}),

I'm sure it's something silly, I just can't figure it out. I'd be grateful for your tips 🙏

Hi @robojiannis :)
Effectively, you can't use the hooks inside a callback, like the actions one.
The good news is that within the params that the callback receives there is a context object that includes all the controllers of the CMS, so you can access the storage source from there.
Hope this helps!

Gotcha, thanks for the swift reply! I'll give it a go
