    If the Adapter Engine Cache is populated with an improper entry in SXI_CACHE, this type of issue may occur. The user can use the following steps to get the issue resolved:

    • Delete the entry if it is incorrect.
    • Now, in order to get the correct Adapter Engine Cache entry populated, resend a message.
