Sensor error when processing Shazzam: TypeError: Cannot read property "result" from null Description The last Shazzam input processed in a Configuration Item discovery will throw the following error if system property glide.util.xml.transformer.handle.utf16_surrogate_pairs is set to false or does not exist in the system.

Sensor error when processing Shazzam: TypeError: Cannot read property "result" from null

Steps to Reproduce

1 → Either delete or set system property glide.util.xml.transformer.handle.utf16_surrogate_pairs to false. 2 → Run discovery or a large range which must also contain wbem ports open 3 → Have a large Shazzam input as an attachment and such input must contains a utf16 surrogate pair 4 → Reprocess the Shazzam input

Workaround Workaround 1 Change Shazzam sensor line:

mapResults(g_array_util.ensureArray(doc.result)); To:

if(!gs.nil(doc) && !gs.nil(doc.result)){ mapResults(g_array_util.ensureArray(doc.result)); } Workaround 2 Set system property glide.util.xml.transformer.handle.utf16_surrogate_pairs to true
