I am using below progress code for calling REST API and getting error message as "argument cannot be null". Progress version is 11.6.3.
oRequest = RequestBuilder :POST(chhttpUrl,oRequestBody):ContentType('application/x-www-form-urlencoded') :AcceptJson():UsingCredentials(oCredentials) :REQUEST.
oResponse = oClient:EXECUTE(oRequest).
Can you please provide the deep detail, how can I resolve this issue?
Thanks in advance.
Can you post more of the code? Can you enable debug alert and post the stack trace?
