It seems that -Infinity isn't valid JSON, so it isn't supported by the JSON parser. So what is the way to handle this so you can at least skip over this value and still get the rest of the valid data back?
When trying to unmarshall the output of
show interfaces transceiver dom thresholds, you sometimes can come across a channel value with -Infinity. This causes the JSON decoder to fail with an error like this:interface-diagnostics: invalid character 'I' in numeric literal"The JSON object in question looks like this:
