Hi nickH. Thanks to your help, I managed somehow to get the example code given by you in the ctrlX Virtual. After modding the code (token, org and bucket) I can see the value 40.2 in the Data Explorer of influxdb, as well as the _measurement and _field properties (see attachment 2023-05-26_11h28_04.png). BUT: The code in the following line produced an error: fmt.Printf("row: %s\n", result.Record().String())   I modded the line in order to see the reason and I could chase that result.Record() seemed to return nil. Here is my modded line:   ... func PrintlnEx(strText string) {     tm := time.Now()     fmt.Printf(fmt.Sprintf("%.4d-%.2d-%.2d %.2d:%.2d:%.2d.%.3d: %s\r\n", tm.Year(), tm.Month(), tm.Day(), tm.Hour(), tm.Minute(), tm.Second(), tm.Nanosecond()/1000000, strText)) }   ...     // Get parser flux query result     PrintlnEx("  Querying...")     result, err := queryAPI.Query(context.Background(), `from(bucket:"bucketHdWin")|> range(start: -1h) |> filter(fn: (r) => r._measurement == "metric")`)     PrintlnEx("  Querying accomplished.")     if err == nil {         if result.Record() != nil {             PrintlnEx(fmt.Sprintf( "    row: %s", result.Record().String() )  )         } else {             PrintlnEx("    ERROR: result.Record() returned nil!")     // <-- The runtime landed here.         }     } else {         PrintlnEx(fmt.Sprintf("    ERROR: %s", err.Error()))     }     // Ensures background processes finishes     PrintlnEx("  Closing DB...")     InfluxDBclient.Close()     PrintlnEx("  Closing DB accomplished.")       And I could see in the trace output that the result.Record() obviously returned nil (see attachment 2023-05-26_11h34_01.png). Any hints what could be wrong? Thanks in advance.                     ... View more

Many thanks for your example. Appreciate it very much! I will try it and hopefully get a little success. ... View more

Hello there.   Unfortunately I didn't get the example in "Get Started" running - somehow I must have missed some correct settings. Well forget to mention I am absolutely a beginner in Linux/Ubuntu world and ctrlX App Builder environment; coming from classical, "old" Windows world. Inbetween I have created an own token and forwarded the port 8086 and create the standard basic project in Visual Studio Code (see attached screenshot). When debugging, I get the message "context deadline exceeded (Client.Timeout exceeded while awaiting headers)".   I guess I am missing quite a lot of things - does somebody know if there is a SDK-like example out there for binding the Influx DB in the ctrlX Core? A very simple example that is capable to run within App Builder for ctrlX Core?  I assume strongly I am missing the right configuration (port forwarding, token, ... and any other prerequisites...). As aforementioned, I am a beginner in Ubuntu/ctrlX Core and may need quite a help in everything  😄 Is there any step-by-step guide how to do it correctly?   ... View more

Hi Nick.   Thank you so much for your prompt reply. As for your questions: Does your InfluxDB Client run also on the ctrlX CORE or does it run outside?     It shall run in the ctrlX CORE or ctrlX Virtual, respectively. Do you use the ctrlX COREvirtual to test it or the real ctrlX CORE?     I am using both of them - virtual for creating the program, core for smoke testing. Which version of the InfluxDB App do you use?     InfluxDB v2.4.0 Do you use the right token, do you use the right url?     I followed the instruction in the "Get Started" within the app installed for ctrlX Core for programming with go (see attached screenshot). What do you mean with don't work, can you give a error message or something?     I try to go run main.go in the Visual Studio Code (main.go copied from "Get Started") - it exits immediately with the code 1 (see screenshot attached as well).   I guess the code from "Get Started" must be running outside ctrlX Core - it appears strongly to me like a standard example from the manufacturer of InfluxDB. Any hints what I can do or modify in the standard code to get it run within ctrlX Core environment? Your help is greatly appreciated. Thanks.   ... View more
