Hi all,
I have some bot variables that I want to set to null at the start of a topic, then later on in the topic I will ask the customer if they want to populate that information. If they don't I want to pass the previously stored null value to a Power Automate cloud flow. If they answer the question, then that value gets stored.
My problem is that I can't get power automate to set the null values to the bot variables, and so it will reroute back to the topic where bot variables are stored and ask for that information again.
Thanks.
Hi @Jondoesflow ,
It's not available yet.

Hi,
It's not even the fact I want to send a null.
It could be anything, I just want the ability the update a variable from a Power Automate flow (the value could be n/a or false) and then save that variable value to the bot variable, unless it gets updated by the user inside the conversational flow.
@Jondoesflow ,
Got it!
Unfortunately, there are many ideas from the Microsoft community that are not available yet. You can vote in all of them and we will keep you posted.

Wow. Ok. Are there any work arounds?
Check the code for your bot variables to make sure that they are being properly set to null at the beginning of the topic. It's possible that there is an error in your code that is preventing the variables from being set correctly.
Make sure that your Power Automate cloud flow is able to handle null values for the variables you're passing to it. If the flow is expecting a non-null value and it receives null, it may fail or generate an error.
Consider using a different value to represent null in your bot variables, such as an empty string or a specific value like "NULL". This can help to differentiate between an intentionally empty value and a value that has not yet been set.
If you're still having trouble, consider using a debugging tool or logging system to help identify where the problem is occurring. This can help you to isolate the issue and find a solution more quickly.
