Hi Nicolas,

please try the argument names without the prefix, e.g.

http://localhost:8083/tbl/swp?_viewClass=directorysynchro:_test_ImportDirectory_zipFile&entityDirectoryGraph=urn:x-evn-master:graph_in_edg&entityDirectoryZipFilePath=/project/filepath

The interpretation of spl:Arguments in SWP (and SPIN) is that only the local name part of the predicate will be used. So for ex:predicate you would use the parameter predicate without the ex:

Hello,
I have a SWP webservice taht is defined the most basically possible, it's a ui:JSONService and it is supposed to use a few parameters defined with spin:constraint :
Argument directorysynchro:entityDirectoryGraph : rdfs:Resource
Argument directorysynchro:entityDirectoryZipFilePath : xsd:string

However, when I use Postman to send the following POST request :
http://localhost:8083/tbl/swp?_viewClass=directorysynchro:_test_ImportDirectory_zipFile&directorysynchro:entityDirectoryGraph=urn:x-evn-master:graph_in_edg&directorysynchro:entityDirectoryZipFilePath=/project/filepath
I instantly get this error

What's strange is that when I try to send the same request as a GET, the service does start (I get logs and ui:dumpScope), however the parameters are not properly bound (I check them with ui:dumpscope but they are all empty)
