Increase FSM Attachment Size Error

Hi IFS Community,

I am trying to increase the attachment file size limit from the default 5MB to 100MB, in which I have changed the app params and IIS server’s maxAllowedContentLength in the web.conf file, however I am faced with the following error message when uploading an attachment: Http failure during parsing for https://localhost/WebClientPortals/api/fsm/performSequentialDependentBatchRequest

Has anyone faced a similar issue and how did you solve this?

Thanks in advance,

Austin
