I dont really know how can I fix it.
I am sure that sending request works - new attribute in Magento was created correctly but error shown up and flow is stopped.
Some more details:

eclipse.buildId=unknown  
java.version=1.8.0_131  
java.vendor=Oracle Corporation  
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=pl_PL  
Command-line arguments:  -os linux -ws gtk -arch x86_64

It works without problems and without errors on my friends Pc. Am I missing some packages on my system?

Answer 1

I solved issue.

You need to remove a jar called async-http-client from you CE Runtime located at /lib/user folder.

Inside your AnyPointStudio installation locate you CE Runtime. It's something like this:

"../Eclipse/plugins/org.mule.tooling.server.3.8.1_6.0.0.201612271237/mule/lib/user"

Located and delete the mentioned jar file, restart your AnyPointStudio and will be fine.

For Standalone Runtime just download the latest version from github and use maven to build it.

Answer 2

There is a bug already raised MULE-8989 at https://www.mulesoft.org/jira/browse/MULE-8989 which is fixed in Mule runtime 3.8.2 https://docs.mulesoft.com/release-notes/mule-3.8.2-release-notes
Try upgrading our mule runtime
