Stuck with relationships. [HELP] :(

I have the following code in a controller:

/**
     * Show Method
     * GET/timesheets/{id}
     */
    public function show($id)
    {
        $record = Auth::user()->company->timesheets()->where('id', $id)->first();
       
        $now = new DateTime($record->weekCommencing);
        $count = 0;
        while($count < 7){
            $dates[] = $now->format('Y-m-d');
            $now->add(new DateInterval('P1D'));
            $count++;
        }

        $placementData = $record->company->placements;
        dd($placementData);

        if($record->agency->placements->count() > 0){
            $placements = array();
            foreach($placementData as $key => $placement){
                $placements[$placement->id] = $placement->name . ' (' . $placement->code . ')';
            }
        } else {
            $placements = array(
                '' => 'No Placements Available',
            );
        }

        // Dates
        $weeks = array();
        $numberOfWeeks = 12;
        $count = 0;
        $now = new DateTime();
        $date = new DateTime('last monday');
        while($count < $numberOfWeeks){
            // Calculate days remaining before these timesheets are deleted
            $since = $now->format('U')-$date->format('U');
            $deletion = ($numberOfWeeks*7)-floor($since/86400);

            // Add the data to the $weeks array
            $weeks[$date->getTimestamp()] = $date->format('d/m/Y');

            // Move the date back seven days
            $date->sub(new DateInterval('P7D'));

            // Increase the counter
            $count++;
        }

        // Store any amendments and pass them to the view
        $amendments = false;
        if($record->amendments){
            $amendments = $record->amendments;
        }

        $canEdit = false;
        if(Auth::user()->role == 'timesheet-manager') {
            $canEdit = true;
        }

        return view('timesheet.form', compact('records', 'canEdit', 'placements', 'weeks', 'amendments', 'days'));

But I keep getting Call to a member function timesheets() on null error and just banging my head against a brick wall here, can't seem to figure it out why this happening.

My data in the DB is all correct and tallies up with each other, but still not no avail.
