Error upon updating the AdSet flexible_spec when it contains inactive Ads

[aamorozov]

I'm updating a bunch of adsets, and not sure why the part of them is throwing the error on update. I haven't found the description of this error in facebook docs nor here hence opening an issue. My use case is to remove flexible_spec field, so I'm pushing an empty array as a value of the property. It works for most of my adset updates but there are certain cases when it doesn't. Thank you for taking a look

I was able to narrow it down a bit - the AdSets that were throwing an error upon update had inactive/paused Ads within them. I think the error message could be more descriptive, but besides that, is expected behavior to not be able to update the AdSet flexible_spec if said AdSet contains inactive Ads?
