ECC -> PI 7.3 Error RUNTIME, ENCRYPTION_KEY, key_initial

[former_member646849]

We have installed a new REST adapter and created structures, synchronous interface, services and channels etc. When we are sending from ECC to PI we receive the below error:

<SAP:Error xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SAP="http://sap.com/xi/XI/Message/30" SOAP:mustUnderstand="1"> 
<SAP:Category>XIServer</SAP:Category>
<SAP:Code area="PERSIST">ENCRYPTION_ERROR</SAP:Code>
<SAP:P1>RUNTIME</SAP:P1> 
<SAP:P2>ENCRYPTION_KEY</SAP:P2>
<SAP:P3>key_initial</SAP:P3>
<SAP:P4/> <SAP:AdditionalText/>
<SAP:ApplicationFaultMessage namespace=""/> <SAP:Stack>An error occurred during encryption: RUNTIME, ENCRYPTION_KEY, key_initial </SAP:Stack>
<SAP:Retry>M</SAP:Retry>
</SAP:Error>

We have been working to understand this error but cannot identify why this happens when sending a message to PI, has anyone came across this error before?

*Solved*

The channel had been setup as a 'sensitive data' channel and we had not setup an encryption key for this. This was a mistake and not actually sensitive data so we removed that flag and the channel now works.

Just in case if you are applying encryption (PGP) to your message over REST Adapter, it won't work as REST adapter does not support message encryption as of now. Check with SAP if there are any updates to this.
