### What happened?
Hello Community, I could run workflows with Asynchronous Web Service without
any problem. Thanks for the shared information!
However, running a pipeline in Web Service gave me the following error
message:
HTTP ERROR 500 javax.servlet.ServletException: Error producing web service
output
URI: /hop/webService/
STATUS: 500
MESSAGE: javax.servlet.ServletException: Error producing web service

CAUSED BY: java.lang.NullPointerException: Cannot invoke

because "component" is null

My web service's json setting is the following:
{
"transformName": "OUTPUT",
"virtualPath": "",
"fieldName": "AuctionDate",
"filename": "${PROJECT_HOME}/Import/Sync_IDA_HUPX.hpl",
"bodyContentVariable": "",
"listingStatus": true,
"name": "syncIdaHupx",
"runConfigurationName": "local",
"contentType": "application/json",
"enabled": true
}
The invoked pipeline is in "waiting" status. The pipeline log halted at
Azure SQL server connection.
I can overcome this with wrapping up in a workflow and run it in async.
Thanks for the clues! Br, Peter
