AEM 6.5 Cloud Version and CIF Addon Installed go in exception when NULL is found in the response

Hi,

 

I am experiencing a problem using CIF, I am using CategoryRetriever from ProductList to query the list of attributes I need to display on a page.

 

When in the getCategory query I receive even a single attribute to null in response, the MagentoGraphqlClient class throws an exception when executing the call.

 

this is the exception:

com.shopify.graphql.support.SchemaViolationError: Invalid value null for field CategoryTree.application_for

 

Is there any way to handle calls with nullable attributes?

maybe some CIF configuration.

 

thanks in advance.

Hi,

There's a patch(fix-error-returning-null-attribute-values.patch) available for download, once downloaded, apply the patch through command line as below 

patch -p1 < fix-error-returning-null-attribute-values.patch

 In your GraphQL, change the "application_for" field to nullable

Then handle null checks in frontend

if (category.application_for !== null) { // Proceed with using category.application_for }

With above you can handle for null case.

 

Thanks,

 

Kind regards,
