Morning Team.
I have a function node that sets some context values.
For some odd reason if I look at my context flow data the name gets changed from "config\_alarm.alarm.zones.01.state" to "config\_alarm.alarm.zones.1.state"
Example Message
```auto
{"_msgid":"ab716e5b1004ff95",
"payload":"arm",
"topic":"/alarm/zone/arm/normal/01,02,03",
"_event":"node:3e0554c5207a26f4"}
```
```auto
var var_str_zone_reference = msg.topic.substring(msg.topic.lastIndexOf("/") + 1);
node.warn(var_str_zone_reference)
var var_array_zone_reference = var_str_zone_reference.split(",");
node.warn(var_array_zone_reference)
for (var var_str_zone_reference of var_array_zone_reference) {
node.warn(var_str_zone_reference)
msg.topic = "config_alarm.alarm.zones." + var_str_zone_reference + ".state";
node.warn(msg.topic);
if (msg.payload == "arm" || msg.payload == "disarm"){
flow.set(msg.topic, msg.payload + "ed");
flow.set
}
}
```

The flow.set() function that writes to context is taking 01 and parsing it as a number 1 and is creating an array in context.
If you want a object with key 01 then use square bracket notation.
e.g.
```auto
msg.topic = "config_alarm.alarm.zones['" + var_str_zone_reference + "'].state";
```
or better still use the best practice form of property names , which should start with a letter or underscore.
e.g.
```auto
msg.topic = "config_alarm.alarm.zones._" + var_str_zone_reference + ".state";
```
p.s. Hi and welcome to the forum.

So if flow.set sees an object key which can be converted to a number it does so and you end up with an array?
Is that a feature of the flow.set code, or of Javascript in general?

Without looking at the underlying flowset code, i can not say. Seems a bit of a strange behaviour, possible bug? But it is not good practice to use numbers as object keys.
