Is there anybody here know much about a program called Reportula? Getting an error but not able to figure out what is causing it.

Below is the error message that is occurring in the program and message being sent to var/root/mail.

ErrorException (E_UNKNOWN)

Argument 1 passed to Illuminate\Database\Grammar:: parameterize() must be of the type array, null given, called in /var/www/reportula/vendor/laravel/framework/src/Illuminate/Database/Query/Grammars/Grammar.php on line 309 and defined

Below is line 309 from Grammar.php
$values = $this->parameterize($where['values']);

From var/root/mail
[Illuminate\Database\QueryException]
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'bacula.file' doesn't
exist (SQL: select count(*) AS filesNumber from `file`)

[PDOException]
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'bacula.file' doesn't
exist

Now table file does exist, verified it but it is named File, not file.
Is the fact the table uses an upper case F critical?

Yes, it is. It's case-sensitive, so "File" isn't the same as "file". If you've got an existing Bacula installation, and can't change the table name, then change the PHP/config file to reference the correct name.
