I have configured SAML with Rocketchat. I’m using WSO2 identity server. There is not problem when i log in, but when i log out, ihave this error:
TypeError [ERR_INVALID_ARG_TYPE] [ERR_INVALID_ARG_TYPE]: The first argument must be one of type string, Buffer, ArrayBuffer, Array, or Array-like Object. Received type undefined at Function.from (buffer.js:305:9) at new Buffer (buffer.js:265:17) at SAML.validateLogoutResponse (app/meteor-accounts-saml/server/saml_utils.js:374:33) at middleware (app/meteor-accounts-saml/server/saml_server.js:604:12) at app/meteor-accounts-saml/server/saml_server.js:704:3 { code: ‘ERR_INVALID_ARG_TYPE’ }

I’m using rocketchat 3.0.3

Because i’m new, i’m allowed to post only two 2 links in this forum. Thus, i cannot post my service provider information and rocketchat saml informations.
