QSYS2.HTTP_GET_BLOB don't return any data

Hi all (again)

In this days i'm try to use QSYS2.HTTP ..

As said in my previous message, i'm try to call a webservice that should
return a csv file (with postman happend this) .

If i run this statement from ACS :



VALUES
CAST(
QSYS2.HTTP_GET_BLOB(
'https://xxxx.com/api/v1/mapping/files',
'{"basicAuth":"myuser,mypass", "sslTolerate":"true",
"header":"Content-Type,application/json; charset=UTF-8 " }'
) AS VARCHAR(2048));



in the acs sql result section, i don't see anything data.



In postman i have setted this parameters:

the url : 'https://xxxx.com/api/v1/mapping/files'

in the Authorization : "Type" Basic Auth - "Username" myuser - "Password"
mypass

then i click in the Send Button i get the result



store_id,seller_name,seller_product_id,partner_product_id,subbyx_sku,price,t
axable,category,keywords,availability,brand,model,description,grade,eans,act

headphones 0954224309",0,apple,airpods max (2024),"Apple Airpods Max

Can some one point me to understand where am i wrong ?

Thanks in advance
