Rule machine seems to be bugged

[mmikeyy]

If I click on the action below, I get the error message displayed after the image:

An unexpected error has occurred trying to load the app. Check Logs for more information.

Error: No signature of method: java.lang.Long.getAt() is applicable for argument types: (java.lang.Integer) values: [0] Possible solutions: getAt(java.lang.String), next(), putAt(java.lang.String, java.lang.Object), wait(), grep(), getClass()

BTW, this rule has been in operation for years and it is executed daily without problems. I just want to edit it, but I can't.

Looks like a pretty old version of rule machine, prior to v3 I think? Which hub firmware version are you running?

Tagging @bravenel.

It displays 'loading app Rule 3.0' momentarily when I click on the app to edit it.

Hubitat Elevation® Platform Version
2.2.4.158
Hardware Version
Rev C-5

Is it recommended to upgrade old rules to the latest version of the rule machine?

No, in general they should continue working as-is. I’m sure it’s possible breaking changes can eventually occur as the rest of the platform is updated. But @bravenel is prob the one that’s most likely to know what the issue could be.

oh... I notice that the error message in the log includes a line number that does not appear on the screen when I try to edit the action. Here's the full logged error message:

groovy.lang.MissingMethodException: No signature of method: java.lang.Long.getAt() is applicable for argument types: (java.lang.Integer) values: [0]
Possible solutions: getAt(java.lang.String), next(), putAt(java.lang.String, java.lang.Object), wait(), grep(), getClass() on line 2282 (selectActionsFalse)

As it is such a small rule, why not just write a new RM4 rule. Not an answer to your question but might be a solution.

As someone else said, you shouldn't have to. But in this case, given the error, you should just remove that rule and recreate it.
