I am using SAS EG ( SAS 9.4.5.0 ) to connect to an REST API using PROC HTTP: It is token based. I get an "< HTTP/1.1 411 Length Required" error. Question: Is there something else I have to specify to avoid this error? First step: to get a token works fine. Step two is a POST where I send a JSON GRAPGQL request together with the token and some extra parameters ( I do the same query in POSTMAN and it works fine) I feed the Token from a file due to the size(>1000 char) I feed the GraphQL from a file as well SAS CODE : PROC HTTP
