I'm trying to post a struct to my server with a POST API call from my typescript frontend.
Attempting to send an empty string for some of my struct values causes json errors because a json value can't be empty. However, the value is empty. I bind to the value with a few different items on my web page, so I want to indicate that the value is truly empty. Replacing it with
Triggers the same error. Specifically, it'll be something like:
What's the correct solution here? The only one I can come up with is creating a keyword placeholder value which should never be real data, and using that to indicate that the data is really blank and then handling that in the backend. I don't like that solution and I'm sure a better one exists. What's the idiomatic fix here? Thanks!

null when creating the json to send to the API call with:let struct: MyStruct = {
value: value || null,
}
Triggers the same error. Specifically, it'll be something like:
