Unexpected data \r\n with Carbon laravel - laravel

Question

I'm trying to get all of the students from a table using "Student::all()". I don't even have carbon in this function. It's not getting students by date or anything. When i try to run the function, I get the error shown in the picture. It's pointing to a carbon file in the vendor folder but I don't know what to change. The data from the database pulls fine in every other function of the program, just not this one exact thing. When I die/dump my function call,I get the students list just fine. Something is simply irritating Carbon for no apparent reason. If I use a carbon parameter, it works, the function doesn't stall, but it does not return the correct data even though the field in the database holds that info. Why would a line break be causing this issue?
This function does not produce the error, but it does not result in the correct data.
public function exportRoster(){
$students = Student::whereDate('updated_at', Carbon::today())->get();
$pdf = PDF::loadView('printRoster', compact('students'), [], ['orientation' => 'L']);
return $pdf->stream('roster'.Carbon::today().'.pdf');
}
This function would obviously have the right data, but it produces the error of "Unexpected data".
public function exportRoster(){
$students = Student::all();
$pdf = PDF::loadView('printRoster', compact('students'), [], ['orientation' => 'L']);
return $pdf->stream('roster.pdf');
}
Just in case it helps, i've also included a screen shot of my database
Here is the table i'm using with my students variable in the printRoster view. If I remove this table, all queries work.
<table style="width:100%;">
<tr>
<th align = "left">Student Name</th>
<th align = "left">Student ID</th>
<th align = "left">District</th>
<th align = "left">School</th>
<th align = "left">Test Date/Time</th>
<th align = "left">Vision</th>
<th align = "left">Color</th>
<th>Nurse</th>
</tr>
#foreach($students as $student)
#php
$grade = array('20/40', '20/50', '20/60', '20/80', '20/100', '20/200', '20/400');
#endphp
<tr>
<td>{{$student->fname.' '.$student->lname}}</td>
<td>{{$student->student_number}}</td>
<td>{{$student->district}}</td>
<td>{{$student->school}}</td>
<td>{{$student->updated_at}}</td>
#if(in_array($student->od_dist, $grade) || in_array($student->os_dist, $grade) || in_array($student->ou_dist, $grade))
<td>Failed</td>
#else
<td>
Passed
</td>
#endif
<td>{{$student->ou_color}}</td>
<td>{{$student->nurse}}</td>
</tr>
#endforeach
</table>

Answer 1

The updated_at column is a timestamp so maybe you need to convert it in a raw date in order to show it. Please try if it works
#foreach($students as $student)
#php
$grade = array('20/40', '20/50', '20/60', '20/80', '20/100', '20/200', '20/400');
#endphp
<tr>
<td>{{$student->fname.' '.$student->lname}}</td>
<td>{{$student->student_number}}</td>
<td>{{$student->district}}</td>
<td>{{$student->school}}</td>
<td>{{date('Y-m-d H:i:s', strtotime($student->updated_at))}}</td>
#if(in_array($student->od_dist, $grade) || in_array($student->os_dist, $grade) || in_array($student->ou_dist, $grade))
<td>Failed</td>
#else
<td>
Passed
</td>
#endif
<td>{{$student->ou_color}}</td>
<td>{{$student->nurse}}</td>
</tr>
#endforeach
Edit
public function exportRoster(){
$students = Student::all();
$pdf = PDF::loadView('printRoster', $students);
$pdf->setPaper('A4', 'landscape');
return $pdf->stream('roster.pdf');
}
