Error in WSDL

[#1]

Hello Everyone,

I'm trying to upload WSDL which was generated from SAP into Apigee. When I traced the Proxy I got 200 as status, but when I'm trying to view the output I'm getting the following output.

<error>

<user>SAPUSER01</user>

<date>20150820</date>

<time>072717</time>

<errorText> WSP Exception caught: Initial value "config key" in method INITIALIZE of </errorText> <bindingKey>D4AE52ABB7AE1ED5889CFEA19083A1B8</bindingKey> <DTObjName/> <configName/> <configType/>

</error>

Can anyone help me on this. Thanks in advance.
