When deploying apps that will accept user uploads it is easy to run into the upload limit. This is, by default, set to 25MB. The error message will look something like "Error: Request failed with status code 413".
Modify the default value - Admin privileges needed
The upload limit is configurable and can be changed by setting the
com.cerebro.domino.computegrid.kubernetes.apps.nginx.clientBodyMaxSizeMiB property to the required megabytes in Admin > Advanced > Central Config.
What is the max limit of this parameter?
The upper limit is dependent upon the browser. I.e., Google Chrome limits the request size to 4GB, ipso facto if you are using Chrome the limit would be 4GB or 4000MB.
