Can you pass Python datetime objects between Azure durable functions?

Question

I am defining a variable in a sub-orchestrator and try to pass it between different durable functions. It's resulting in a non-deterministic workflow. In the docs (https://learn.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-code-constraints?tabs=python#dates-and-times) it says that you can't use datetime.now() but I'm not using the now() method. Rather I'm just setting the datetime to a static date and time. The docs also say the list of constraints isn't comprehensive so maybe I'm missing something, but in general is it possible to pass datetime objects between durable functions?

@Clay Casper ,

"I am defining a variable in a sub-orchestrator and try to pass it between different durable functions."

Are you referring to activity functions when you mention "different durable functions" ?

Please let me know. Also you will have to avoid using static variables in durable functions

Avoid using static variables in orchestrator functions because their values can change over time, resulting in nondeterministic runtime behavior. Instead, use constants, or limit the use of static variables to activity functions.
