When using SNMPWALK to JSON preprocessing step it breaks if we get an unexpected NULL anywhere before the OID's we're looking for: .1.3.6.1.2.1.10.7.2.1.15.1 = NULL .1.3.6.1.2.1.31.1.1.1.1.1 = STRING: wan1 .1.3.6.1.2.1.31.1.1.1.1.2 = STRING: wan2 I'm looking for OID .1.3.6.1.2.1.31.1.1.1.1 here, but error states that: no data was found At the same time, this works fine:
.1.3.6.1.2.1.10.7.2.1.15.1 = null
.1.3.6.1.2.1.31.1.1.1.1.1 = STRING: wan1
.1.3.6.1.2.1.31.1.1.1.1.2 = STRING: wan2
And also this works: .1.3.6.1.2.1.10.7.2.1.15.1 = STRING: NULL .1.3.6.1.2.1.31.1.1.1.1.1 = STRING: wan1 .1.3.6.1.2.1.31.1.1.1.1.2 = STRING: wan2 This can probably be considered incorrect output from the device, but still we should not break monitoring of anything else because of this.

(1) Another case where things fail:
unable to extract value for given OID: invalid OID format
