Error adding XSD script to SOAP Message Validation policy

Google Cloud Apigee
1

When attaching SOAP Message Validation in API proxy, am getting error while adding .xsd file to soap message validation policy

  1. When creating policy, if I select file type as “XSD” and Script file as “Create new script”, am getting error message “Script has no source, it should be a new one, an imported one or an existing one.”

  2. When I pre-populate xsd script in resources and add my .xsd file to the resources, then when i come to add policy->select Soap message validation policy → select existing .xsd script, the error says
    “File extension does not match selected file type. Found: .xsd; Expected: .wsdl”

Hi, thanks for reporting this. Can you attach a screenshot for each of these two errors?

Hi,

Can you confirm which version of Apigee you are on? I gave this a try on Apigee X using the GCP Console based UI and the behavior works as expected. However, the screen shot looks like one of the older user experiences.

Hi @ark123 , @malashree ,

I was able to recreated the issue in an Apigee Edge SaaS organization. Is that the version of Apigee you are using? I will log this as a bug internally for our team to address. I’d also suggest log a support ticket so you can be kept up to date on this.

On a positive note I did find a workaround (detailed below) so you don’t have to wait on a fix to be deployed.

  1. Within the Apigee Edge UI, create a new SOAP Message Validation policy and uncheck the Include Schema box when you add the policy.
  2. Delete the SOAP-Message-Validation-1.wsdl that gets created.
  3. Add your XSD file as a new resource to the proxy.
  4. Update the ResourceURL element within the policy you created in step 1, to reference the XSD you just created in step 3. For example: xsd://note-schema.xsd

See below for an example proxy I have working using this workaround for reference. The proxy follows this example.

MessageValidation policy:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<MessageValidation continueOnError="false" enabled="true" name="MV-Message-Validator">
    <DisplayName>MV-Message-Validator</DisplayName>
    <Properties/>
    <Source>request</Source>
    <ResourceURL>xsd://note-schema.xsd</ResourceURL>
</MessageValidation>

Schema (note-schema.xsd):

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="note">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="to" type="xs:string"/>
        <xs:element name="from" type="xs:string"/>
        <xs:element name="heading" type="xs:string"/>
        <xs:element name="body" type="xs:string"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

Default.xml

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ProxyEndpoint name="default">
    <PreFlow name="PreFlow">
        <Request>
            <Step>
