BayeuxParameters Streaming API version?

[jackydec]

In the interface BayeuxParameters, you specify the Streaming API version to 39.0.

Is this correct?

When creating the pushtopic as in the example (https://developer.salesforce.com/docs/atlas.en-us.api_streaming.meta/api_streaming/create_a_pushtopic.htm#create_a_pushtopic) i cannot create it with pushTopic.ApiVersion = 39.0; Salesforce returns an error : Line: 10, Column: 1 System.DmlException: Insert failed. First exception on row 0; first error: INVALID_FIELD, Invalid ApiVersion: [ApiVersion]

If i change the api version to 38.0, SFDC creates the pushtopic without any problem.

Do the versions of the API in your code need to match the version in the PushTopic ?

When i try to run the LoginExample, i get following stacktrace ::

I'm not behind a proxy server and when i'm consulting the login history in SFDC, i can see a succesfull login.

My params for the LoginExample are "user password /topic/InvoiceStatementUpdates"

what am i doing wrong?

NA39 is still on API version 38.0.

[sourabhrajput]

I faced similar issue, but I am facing another additional issue, even after specifying API version 37.0 Or 38.0... I am getting following response back [{"channel":"/meta/handshake","error":"400::Unsupported API version. Only API versions '35.0' and '36.0' are supported.","successful":false}] and when I specify API version 36.0 I code is working fine and recieving event via PushTopic

Not able to find out what am i doing wrong?
