Issue Summary

Using "plusMonths" in the smart value works well in most situations. However, it may lead to errors in certain cases where the resulting date becomes invalid after the addition. For example, adding 1 month to 31 Jan would result in 31 Feb, which is an invalid date.

Steps to Reproduce

1. Create an automation rule to fetch a date value
2. Now add the fetched date value with 1 month using the smart value "plusMonths" and assign it to a variable
3. Print the smart value variable in the audit log

Expected Results

The date value should automatically get adjusted to the 1st of next month

Actual Results

The below error is thrown in the Automation audit log:

Failed to get value for now.plusMonths(1): {{now.plusMonths(1)]}} 

Workaround

Currently, there is no known workaround for this behaviour. A workaround will be added here when available
