Error en la muestra de transportitstas externos

[deustotechMobility]

Buenos días,

 

he creado un módulo que añade transportistas en prestashop obtenidos a traves de una API externo a partir de una serie de parámetros estipulados.

 

La addición de dichos métodos de transporte a la base de datos de prestashop se realiza de forma adecuada, sin embargo a la hora de mostrar los transportes en el paso 4: Transporte sale el siguiente error:

 

Warning: strip_tags() expects parameter 1 to be string, array given in C:\xampp\htdocs\prestashop\classes\db\Db.php on line 815

 

El método de instalación de transportes es el siguiente:
