Are you calling it with no params

stocky-restaurant-98004 · Answer

I believe you have to specify the outputs it won t automatically walk your component

``` We also need to register all the expected outputs for this component resource that will get returned by default self register outputs virtual network virtual network subnet subnet ```

And it s saying `your component virtual network` is not defined

NM I see above

Can you give me a few lines of code around where the stack trace is

stocky-restaurant-98004 · Answer

The `self` is a little confusing to me but I am probably missing something

quaint-tailor-52411 · Answer

sorry i ended up added self so I could access it as a member since `register outputs` was not working

quaint-tailor-52411 · Answer

some of pulumi examples does this also

quaint-tailor-52411 · Answer

```import pulumi from pulumi azure native import network class MyComponent pulumi ComponentResource def init self name props=None opts=None super init pkg network MyComponent name=name props=None opts=opts child opts = pulumi ResourceOptions parent=self virtual network = network VirtualNetwork name address space=network AddressSpaceArgs address prefixes= 10 0 0 0 8 location= westus resource group name= myRG virtual network name= vnetName opts=pulumi ResourceOptions parent=self self register outputs virtual network virtual network ```

quaint-tailor-52411 · Answer

```import component mycomponent = component MyComponent mycomponent mycomponent virtual network```

quaint-tailor-52411 · Answer

``` error Program failed with an unhandled exception Traceback most recent call last File Users james repos cyclecloud vm main py line 22 in lt module gt mycomponent virtual network AttributeError MyComponent object has no attribute virtual network ```

Giving this code a hard stare

stocky-restaurant-98004 · Answer

Let me try to repro this real quick

stocky-restaurant-98004 · Answer

What version of pulumi are you using

quaint-tailor-52411 · Answer

``` venv jamess MacBook Pro vm james$ pulumi version v3 39 3```

Can you verify that virtual network creates successfully by copy pasting outside of the component

quaint-tailor-52411 · Answer

this was a dummy example but i was able to create vnets with it yes

stocky-restaurant-98004 · Answer

I m getting the same Let me double check what the correct way is

stocky-restaurant-98004 · Answer

It should be `self virtual network = ` and you do not need to call `register outputs` I ll submit a PR to update the docs and my apologies for hitting this Our docs should be clearer on this subject

quaint-tailor-52411 · Answer

ok so this is just standard python then

quaint-tailor-52411 · Answer

since you re going to update the docs

quaint-tailor-52411 · Answer

i think this does nothing also `child opts = pulumi ResourceOptions parent=self `

stocky-restaurant-98004 · Answer

You do need to set `parent=self` for each resource in the component because that s how you inherit the provider

quaint-tailor-52411 · Answer

yeah but this was just in the contructor with no resource
