Resource api 1.0 throws Nullpointer exception

abehari · October 14, 2021, 6:43pm

Hello, we’re trying to use the resource api 1.0, but when we try to access the api it throws a nullpointerexception. If we provide version 0.9 in the Accept-Version, then it works. Not with version 1.0

[HstDelegateeFilterBean.doFilter:642] ContainerException for 'Request{ method='GET', scheme='https', host='local.company.nl', requestURI='/site/resourceapi/test/products', queryString='null'}':
org.hippoecm.hst.core.container.ContainerException: java.lang.NullPointerException

Have anyone encounter this problem? What can be the problem as we don’t know how to solve this.

Thanks in advance

Hi,
I’ve not seen this, curious about the rest of the stack trace though!

If you set log level to DEBUG of org.hippoecm.hst.container.HstDelegateeFilterBean, using the /logging/ servlet, you will see that.

Hi,

I tired debugging but still not able to diagnose this problem.

Hi,

A colleague debugged the code and found that the nullpointer is thrown in the class

org.hippoecm.hst.pagemodelapi.v10.core.container.PageModelAggregationValve

On the lines 435 and 448:

 private Map<String, String> getResidualParameters(final ComponentConfiguration compConfig) {
        final ResolvedSiteMapItem resolvedSiteMapItem = RequestContextProvider.get().getResolvedSiteMapItem();

        final Map<String, String> parameters = compConfig.getParameters(resolvedSiteMapItem);

        String[] variants = getVariants(compConfig);
        List<String> paramsInfoNames = getParamsInfoNames(compConfig);
        return parameters.entrySet().stream()
            .filter(entry -> !StringUtils.startsWithAny(entry.getKey(), variants))
            .filter(entry -> !paramsInfoNames.contains(entry.getKey()))
            .filter(entry -> !HIDE_PARAMETER_NAME.equals(entry.getKey()))
            .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue));
    }

The NPE is trigger most likely from using placeholders in one of our yaml files:

definitions:
  config:
    /hst:hst/hst:configurations/cbhippowebsite/hst:abstractpages/base:
      jcr:primaryType: hst:component
      hst:componentclassname: nl.test.BaseLayoutComponent
      hst:parameternames: [analytics.logged-in]
      hst:parametervalues: [Loggedin']
      hst:template: base
      /head-meta:
        jcr:primaryType: hst:component
        hst:componentclassname: nl.test.HeadMetaComponent
        hst:parameternames: [excludeTealium]
        hst:parametervalues: ['${excludeTealium}']
        hst:template: base-head-meta
        /metadata:
          jcr:primaryType: hst:component
          hst:componentclassname: nl.test.MetadataComponent
          hst:template: base-metadata
        /article-structured-data:
          jcr:primaryType: hst:component
          hst:componentclassname: nl.test.ArticleStructuredDataComponent
          hst:template: article-structured-data
      /header:
        jcr:primaryType: hst:component
        hst:componentclassname: nl.test.HeaderNavigationComponent
        hst:parameternames: [secondaryNavigation, lightHeader]
        hst:parametervalues: ['${secondaryNavigation}', '${lightHeader}']
        hst:template: faas-template
      /footer:
        jcr:primaryType: hst:component
        hst:componentclassname: nl.test.FooterComponent
        hst:parameternames: [lightFooter]
        hst:parametervalues: ['${lightFooter}']
        hst:template: base-footer
      /analytics:
        jcr:primaryType: hst:component
        hst:componentclassname: nl.test.AnalyticsComponent
        hst:template: base-analytics
      /main:
        jcr:primaryType: hst:component
        hst:template: base-main
      /cookie-consent:
        jcr:primaryType: hst:component
        hst:componentclassname: nl.test.CookieConsentComponent
        hst:template: template-engine

Same config code works perfectly with 0.9:

org.hippoecm.hst.pagemodelapi.v09.core.container.PageModelAggregationValve

So were you able to pinpoint the NPE a bit further? Is it perhaps caused by the placeholders replaced by null because the value isn’t there?

abehari · November 11, 2021, 8:31am

That could be the problem, but how come it works with 0.9? It puzzles me.
