Error installing Dynamic Routes

Just upgraded FreePBX 12 to 13
All is working fine.

Trying to install Dynamic Routes ( 13.0.3 ) module I get this error :

SQLSTATE[42000]: Syntax error or access violation: 1068 Multiple primary key defined
/var/www/html/admin/modules/dynroute/Dynroute.class.php
."TABLE_CATALOG = ‘def’ AND TABLE_SCHEMA = DATABASE() AND “
.”TABLE_NAME = ‘$table’ AND INDEX_NAME = ‘PRIMARY’ ";
$results = sql($sql, “getAll”,DB_FETCHMODE_ASSOC);
if (empty($results)) {
$sql = “ALTER TABLE $table
ADD PRIMARY KEY (dynroute_id,selection);”;
$sth = $this->db->prepare($sql);
$sth->execute();
}
} catch(PDOException $e) {

Any hint please ??

Looks like a bug in the Dynroutes module. Dynroutes is not supported here, unless the dev happens to notice your thread, best to contact them directly.

I supposed…just to know if it was an already know issue…
I’ll try to contact developer.
Thanks
