    Default Binary data in REST step?

    Hi all,

    I can't figure out what I'm doing wrong so Idecided to ask the experts
    My transformation is getting an image that is base64 encoded by XML. In a Javascript-step I use org.Apache.commons.codec.binary.Base64.decodeBase64() to get the original bytes back. From this step I have an outgoing step with type "binary" with that data.
    When I then put in in a file with the "Text file output" step, I can see the image, everything is fine.

    Now I try to send the binary data via REST to a CUBA-application to an endpoint that puts the content of the body in a file. This also works, BUT: the filesize increases from 45kb to 71kb, the content is very similar so I suspect that somewhere the binary data gets corrupted. Maybe there is a UTF-8 conversion happening??

    When I use Postman (a REST-client) and send the file to the CUBA-application everything works fine so I assume the problem lies in the REST-step but I can't figure out what settings could cause the trouble.

    Any advice?

    Thanks in advance!

    Does the unexpected conversion happen if you set the "Application type" to "OCTET STREAM"?
    So long, and thanks for all the fish.

    I tried "OCTET SREAM" as well as "TEXT PLAIN" and it happens everytime. Honestly, I don't know what this setting has an effect.
