Ok, there are 2 cases.   1.  You use Base64EncodeContent to encode your image and after that with ExtractText there you write the content of your flowfile to an attribute. There you have to set the property Maximum Capture Group Length to your desired length. I would prefer that you also set Maximum Buffer Size to ~10 MB that the process gets fully buffered.   2.  Use Processor ExecuteStreamCommand  Properties: Command Arguments: -w 0 Command Path: base64 Output Destination Attribute: attribute.base64 Max Attribute Length: your desired length   If you dont work with one of those 2 cases, then please describe your flow 🙂     ...

Hello,   this does not seem to be possible for me. You can use before JOLTTransformation the Processor EvaluateJsonPath to store the date to an attribute and afterwards you could do your convertation with expression language function in JOLT.   Greetings ... View more
