I’m using Spring Boot 2.7 and Java 11 HTTP Client to do a GraphQL Request like this:

    private HttpRequest gqlRequest() {
        URI uri = URI.create(dataUrl);
        return HttpRequest.newBuilder()
                          .uri(uri)
                          .header(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
                          .header(HttpHeaders.AUTHORIZATION, "Bearer " + sessionToken)
                          .POST(HttpRequest.BodyPublishers.ofString(gqlRequest))
                          .build();
    }

When my gqlRequest is a Java Text Block it does not work. I get a 400 Bad Request.

    private final String gqlRequest = """
            query ChargingStationAndConnector{
                connector(id: "05f113a5-d662-4f00-bf31-fc18e10a6306"){
                    id
                    evseId
                    connectorType{
                        id
                        chargePointType
                    }
                }
                station:cp(id: "33842d46-3b53-4f7f-b2a9-cc062658e8c7"){
                    id
                    address
                    city
                    zip
                    country
                }
            }""";

However when i put this GQL into one line and add the tabulation and new line chars then it works.

String gqlRequest = "{"query":"query ChargingStationAndConnector{\n\tconnector(id: \"05f113a5-d662-4f00-bf31-fc18e10a6306\"){\n\t\tid\n\t\tevseId\n\t\tconnectorType{\n\t\t\tid\n\t\t\tchargePointType\n\t\t}\n\t}\n\tstation:cp(id: \"33842d46-3b53-4f7f-b2a9-cc062658e8c7\"){\n\t\tid\n\t\taddress\n\t\tcity\n\t\tzip\n\t\tcountry\n\t}\n}","operationName":"ChargingStationAndConnector"}";

Why and can i work with a theblock due to it’s much better readability?
