Fetching external content was not successful. Received http 401 unauthorized

I got following error when sending an image to a line conversation:

Caused by: org.flowable.common.engine.api.FlowableExeption: Fetching external content was not successful. Received http 401 unauthorized ..
at com.flowable.engage.external.system.line.LineInboundJmsListener.receivedMessage(LineInboundJmsListener.java:68)

hey @FlowBallon,

The stacktrace contains classes from the Flowable Enterprise offering. This forum is for the Open Source. The enterprise forum is at https://forum.flowable.com/.

In any case, if you are getting this it looks like some misconfiguration. I would advise you to validate that your LINE configuration is as it is explained in our installation guide. If you are still having problems you are welcome to open an issue through our support desk.

Cheers,
Filip
