Hi all, We call a REST Service and get an 'error 400 Bad Request' back. The request is created based on a number of products the user has selected. The more products, the longer the request. We're thinking the error comes back because the request might be too long, with a less number of products the request is build up in the same structure (but its shorter) and no error is received. For the call REST activity its possible to set the timeout on request. But does anyone know if there is a maximum string length for a request defined in Mendix? And if so, where can I find this? Thanks, Vianey de Lima
