sendNotification not working inside DSL script in a rule

[Thinqer77]

I’m struggling to get sendNotification to work inside a DSL script in a rule built using the UI. I’ve created a very simple rule that fires every minute and have added two actions: the first executes a one line DSL script containing the sendNotification command and the second action uses the built-in UI ‘send a notification’ option. Both target the same email address (I’ve double checked this!) I get the message from the UI ‘send a notification’ but not the one from inside the DSL script.

Issue more fully outlined and explored here:

https://community.openhab.org/t/sendnotification-not-working-inside-dsl-script-in-a-rule/153811/11

Expected Behavior

I should receive the notification on my mobile device from the sendNotification inside the DSL rule.

Current Behavior

Here is the rule definition:

Inside the script is the following (email address changed but matched the one I sign in to myOpenHAB with):

sendNotification("myemail@address.com", "Hello world!")

When the rule triggers I get the notification from the UI defined send notification, but not the one from the Rule DSL script. If I remove the UI send notification item then I still don't get a notification.

I then further tested by setting up the following:

1. Text file rule in a file called ‘TestNotification.rules’ with the following rule in it:

rule "TestSendNotification"
    when
        Time cron "0 * * * * ? *"
    then
        logInfo("Alerts", "About to send my notification 2")
        sendNotification("myemail@address.com", "Hello World 2!")
        logInfo("Alerts", "My notification 2 sent!")
end

2. Rule defined in UI as above but with the UI notification set up as well as the DSL script notification as follows:

logInfo("Alerts", "About to send my notification")
sendNotification("myemail@address.com", "Hello world!")
logInfo("Alerts", "My notification sent!")

Here are the log entries I get with the above two rules set up:

The first block of the log shows the text file based rule running. You can see there are two lines in there, one saying ‘sending notification’ and one saying ‘Sending message’, which seems a bit odd. In any case, the next line says no connection (then my logInfo line gets inserted).

The second block is for the UI defined rule and it also has the two ‘sending Notification’ and ‘Sending message’ lines and the ‘no connection’ message (all of which I assume relate to the script based action, which is triggered first). Then a few lines later the UI defined message gets sent with a log entry of ‘Sending message’ but not followed with a ‘no connection’ error.

I don’t get any of the notifications from the two script based rules but I do get the one from the UI defined one. I need to use the script based one as I want to include variable text in the message depending on the state of certain items which isn’t possible using the UI defined notification.

I also created a Blockly based rule and it delivers the notification without issue.

Possible Solution

Steps to Reproduce (for Bugs)

See above for setup

Context

I'm trying to send a variable text string (based on the values of multiple items, including and excluding some depending on other items) and am trying to build it in Rule DSL scripting because the UI rule definition doesn't allow me to send variables or compose strings.

Your Environment
