Steps to reproduce:

1. Create a walk item and collect values with out-of-range indexes, (e.g. IF-MIB::ifName.4194322432)
2. Create a dependent discovery rule and a prototype item to query the walk
3. Execute the walk item

Result:
An error message is presented: "Failed: unable to extract value for given OID: no data was found" although if you go through the walk value, the data is present. See attached image.

Expected:
Expected the out-of-range index to be parsed as valid, even though not in spec.
