@enam Have a slight mistake in my NiFi Expression Language (NEL) statement in my above post. Should be as follows instead: Property = filename Value = ${filename:substringBeforeLast('.')}-${UUID()}.${filename:substringAfterLast('.')} Thanks, Matt ... View more

Hi, The processor sure changed in 2.0 from before , so few things I will check : - Make sure the Request Bondy Enabled is set to true - Make sure the Request Content-Type is set to : multipart/form-data - Make sure to set the Request Multipart Form-Data Name to: file - Once you set the property above, the property Request Multipart Form-Data Filename Enabled becomes visible , make sure it sets to true and it will use the filename attribute in the Content-Disposition header. - Make sure to set the  Response Generation Required property to: true (default false) - Finally, I dont think you need the Content-Disposition dynamic property since its already been set through the above properties. I honestly dont like how in 2.0 there is a lot of visibility dependency with some of the properties where their visibility depends on setting the value of others. It makes it confusing specially when you read the documentation and struggle to find all the mentioned properties until you set the right values. I would rather if its all showing  or at least less visibility dependency on some of them.  Let me know if that works for you or not. If it does, please accept solution. Thanks         ... View more

You can also right click on a given process group and select Download Flow Definition which will save the process group in json format.   If that helps please accept solution. Thanks ... View more

@enam   I cant see the entire configuration of the second InvokeHTTP so I am not sure if you are passing those new attributes into the HTTP URL.   If you are not doing that, I think the solution you are looking for is to have the AttributesToJson set Destination to FlowFile Content.  Then when you post that to invokeHttp,  those values are seen as the post content.     ...
