Hi,

my problem is, that I can’t pass parameters from my ExtJs application to my defined functions in the database (postgreSQL).  
I found several solutions in internet how to send the params to dreamfactory, but none of them functions.

I always get a 500 Response, that the handedover params don’t fit their definition in the database.

If I call /api/v2/db/\_func?ids=functionname in Postman for example I get the following result:  
{  
“resource”: [  
{  
“alias”: null,  
“name”: “functionname”,  
“label”: “functionname”,  
“description”: null,  
“native”: [],  
“return\_type”: “integer”,  
“return\_schema”: [],  
“params”: [],  
“access”: 31  
}  
]  
}

So here I can see, that according to dreamfactory it don’t even exist parameters.  
But they are defined in the definition of the functions in the database and all worked correctly when I was using Dreamfactory 1.9. I recently updated to Dreamfactory 2.4.2.

How is it, that I have this error?  
What must I do, that this works correctly?  
Thank you in advance for any hint.  
Best regards
