Hello Community.  I am hoping someone can assist.  We just upgraded our environment to 7.11.9 NW and SAP MII to 12.2.  We are getting the following error consistently from our one instance of MII NW.

" java.lang.NullpointerException: while trying to get the length of a null array loaded from field com.sap.engine.session.exec.ClientContextImpl.flowInfo of an object loaded from local variable 'this' "

Anyone know what the cause is or the resolution?

Can you provide a screenshot or attach the transaction/template from which the error is being generated?  Are there other instances of MII NW which do not show the error?

The error is actually being captured within the logs (defaultTrace).  They are not seeing the error (we believe) within their session.  The issue is currently happening at one of our three instances.  All instances are on the same release.

Hi Ryan,

Can you post the contents of the log and where the error is happening in the transation or template?

It might also help if you have a trace of the same function processing successfully.

Thanks, Mike

Thanks Michael,

We figured out what was happening in XMII with the assistance of SAP.  From the upgrade, two XMII tables did not have the contents deleted, causing us to have the issue.  The two tables were T_CHUNK and T_SESSION. The process is below:

1. Stop SAP Services to MII
2. Delete all rows from the two tables.
3. Start the SAP Services for MII

Many thanks for posting the solution!
