DescribeSObject call using the v45.0 Partner API are failing due to a complex type(json) that isn't defined in the WSDL

Fixed - Summer '19 Patch 13.0

Some calls to describeSObjects() using the older versions of the Partner API are failing due to a complex type that isn't defined in the WSDL being returned.

In Summer ‘19, Real-Time Event Monitoring Beta was released and made available to orgs with Event Monitoring license. As a result, some objects which were originally implemented in earlier versions of the API may now be visible. Some of the objects include a field with JSON data type which were not defined in earlier versions of the WSDL when these objects were not available, so describe calls referencing these objects may fail.

1.Call describeSObjects() using the v45.0 or older Partner API against a v46.0 org.

2. The call will fail with this error message ‘System.InvalidOperationException: Instance validation error: 'tns:json' is not a valid value for soapType.’

1) Use the latest partner WSDL.

2) Update your pre-v46-versioned partner wsdl with

<simpleType name="json">
<restriction base="xsd:string"/>
below <simpleType name="ID">...</simpleType>
<enumeration value="json"/>
to <simpleType name="fieldType">
<enumeration value="tns:json"/>
To <simpleType name="soapType">

3) Ask Salesforce support to temporarily disable the Real-Time Event Monitoring Beta.

Note: Don’t build integrations using the Real-Time Event Monitoring (Beta) objects in versions of the API less than v46. In order to use the objects in the Real-Time Event Monitoring (Beta) use the latest version of the API.
