alert_policy.id()

is an output type, it’s value is not known at program execution time (unless you

apply

it). You would typically register it as an output.

Itay, thanks so much for your response. If I can’t get this value at runtime, how do I create other resources that are dependent on it in the same stack? When you say apply, do you mean something like:

print("alert_policy.id=" + alert_policy.id.apply(lambda id: id) )

And when you say resister output, do you mean something like this:

pulumi.export('policyid',  alert_policy.id)

So you have a couple of options. If something needs that ID explicitly it’ll typically take an input and you can use that. If you need to compute a value based on this, you can use apply to compute the value (and that’ll also be an output, so not resolved in normal execution), or I believe Python has a type of string formatting for values as well that’ll also create an output. I know Go has one.

Basically, yes, I’m trying to use this ID in the creation of another resource later in the code, something like this:

resource1 = x(...)

resource2 = y(resource1.id, ...)

It seems like a very basic thing to do, and I read in the doc that when you provide the output of one resource as an input to another, Pulumi should work the dependencies out and the value should be available when it is needed. But that doesn’t seem to be the case here. I did try the apply code I wrote above, but it returns the same error, the input to resource2 (which is an output of resource1) still does not have a value.

Can you be more explicit about what’s the other resource you want to create? What’s the code you have that’s not working?

sure, here is the actual code. I’m using the New Relic library to create a monitor that pings a website every 5 minutes or so.

import pulumi
import pulumi_newrelic as newrelic
import pprint

alert_policy=newrelic.AlertPolicy("DAI-SHARED-DEV-OPERATIONS-WORKFLOW-CREATED", 
    incident_preference="PER_POLICY",
    name="DAI-SHARED-DEV-OPERATIONS-WORKFLOW-CREATED")

    critical = newrelic.synthetics.MultiLocationAlertConditionCriticalArgs(threshold = 3),
    warning = newrelic.synthetics.MultiLocationAlertConditionWarningArgs(threshold=1)
)

When run, I get this:

    error: newrelic:synthetics/multiLocationAlertCondition:MultiLocationAlertCondition resource 'Alert Condition 1 (script created)' has a problem: Attribute must be a whole number, got 1510434. Examine values at 'MultiLocationAlertCondition.PolicyId'.

Funny thing is, Pulumi is complaining “Attribute must be a whole number, got 1510434”, and 1510434 is clearly a whole number if I remember my math correctly. And I did check NewRelic, the created AlertPolicy does have the value of 1510434.

Can you try something like this (on my phone so this is pseudo code):

policyid = alertpolicy.id.apply(lambda myid: int(myid))

And then try and pass policyid to the alert you’re creating

Holy cow, that worked! Thanks so much for the help!

This kind of seems like a bug. You should open a ticket with the info.
