Export to excel function get no response from online server


I’m trying to export the Gantt to excel file, I added the attribute (visual:true) to the function but I get no response from the online server.
How can I export the view to Excel or how do I know the weight of the file I’m about to generate. i known The Max request size is 40MB. my list is not to big.
I work according to the site guide.


40Mb - is the maximal request size for MSP files and only if you add a different export server address. By default, the request size cannot be larger than 10Mb.
Unfortunately, there is no built-in way to see the request size. If you export with the raw:true option, the size will be bigger. It is something like 20Mb for 20000 tasks. Without that option, it is around 5Mb for 20000 tasks.
The dev team will add a way to see the request side, but I cannot give any ETA.

Probably, the issue is related to Gantt configuration, but it is hard to suggest what might be wrong as I don’t see your code.
