REST Receiver Error - URL placeholder mytoken is not configured, or has an empty value

[Former Member]

Hi Everyone

I've got a SOAP to REST scenario in which I write a custom value to the Dynamic Configuration (Adapter Specific Message Attributes) and need to then use it in the REST receiver channel using Pattern Variable Replacement in the HTTP Headers section of the channel.

I can see the entry in the DynamicConfiguration section of my SOAP Header of the inbound message but I am getting the error URL placeholder mytoken is not configured, or has an empty value

This is my sender SOAP Channel -

And my receiver channel -

DynamicConfiguration -

What am I missing here?

Thanks in advance!

Regards
