Hi,
I'm running into a timeout issue when attempting to delete a large feature layer. I receive "Unable to delete item" at exactly 60 seconds in the network devtool logs.
I've seen similar issues discussed in Esri Community where a HTTPS operation timeout occurs if it takes longer than 60 seconds. Some examples below:
I do not believe this timeout is coming from any gateways/reverse proxies and also not from any Server service settings. Could it be something to do with javascript, browser, and synchronous requests having a 60 second timeout? Is there a way to perform an asynchronous delete request to get around this?
