New isInt() / isInt('<string>') Function Doesn't Work

[eliotcole]

When one clicks for available functions in Power Automate, there is a nice new function (which we've been waiting on for a while!) which declares whether or not a passed string is an integer or not with a true/false response.

https://docs.microsoft.com/en-us/azure/logic-apps/workflow-definition-language-functions-reference#i...

Unfortunately, after trying this on both paid and unpaid Power Automate accounts, it doesn't work.

I'm aware that this same list is also relevant for Azure Logic apps, however I would think that if the feature set is different for this service you would've definitely set a different set for the Power Automate functions reference.

Running this function either on a variable, compose, or just a string, produces the following error:

Unable to process template language expressions in action 'Initialize_isIntVAR' inputs at line '0' and column '0': 'The template function 'isInt' is not defined or not valid.'.

Could you flick whatever switch needs flicking to make it work, please? 🙂

I note that this has now disappeared from said documentation.

Is this a future function that is in the works?

EDIT - 

I see here that it was added and removed by Dustin, so I'm going to wait hopefully for a future iterative update of the available functions!

(slide in an isErr() and you'll have a super winner!)
