Hi Gustaf, I’ve noticed you had uploaded a simple client interface to websocket-procs.tcl. https://bitbucket.org/naviserver/websocket/src/master/websocket-procs.tcl <https://bitbucket.org/naviserver/websocket/src/master/websocket-procs.tcl>
However, I hit another error related to [dict], because the url doesn’t return a path, when [dict get $d path] runs. The websocket sample is "wss://javascript.info/article/websocket/demo/hello" Best wishes, I [12/Jul/2020:21:03:33][22342.7efbf37fe700][-conn:iurix:0:36-] Error: can't read "path": no such variable while executing "append request_url /$path" (procedure "ws::client::open" line 19) invoked from within "ws::client::open $url" ("uplevel" body line 8) invoked from within "uplevel { ns_log Notice "Running TCL script luna.tcl" #set url "ws://192.199.241.130:5008/api/subscribe?auth_token=9fb6e731-b342-4952-b0c1-aa1d0..."
