(aws-scheduler-targets-alpha): Cannot use imported function ARN with LambdaInvoke target #29284
Description
Describe the bug
I'm trying to invoke a "singleton" lambda created in another Stack. I expose the Function ARN via a CloudFormation output. If the lambda function ARN is being imported from a CFN output (e.g., Fn.importValue), even with sameEnvironment: true, an error is thrown at synth time.
Expected Behavior
I expected the validation for the region to be ignored if I use Lambda.fromFunctionAttributes with the sameEnvironment value set to true.
Current Behavior
I get this error:
/private/tmp/bug-report/node_modules/@aws-cdk/aws-scheduler-targets-alpha/lib/lambda-invoke.ts:21
throw new Error(`Cannot assign function in region ${this.func.env.region} to the schedule ${Names.nodeUniqueId(schedule.node)} in region ${schedule.env.region}. Both the schedule and the function must be in the same region.`);
^
Error: Cannot assign function in region ${Token[TOKEN.22]} to the schedule BugReportStackSchedule10380292 in region us-east-2. Both the schedule and the function must be in the same region.

Reproduction Steps
import { Schedule, ScheduleExpression } from '@aws-cdk/aws-scheduler-alpha';
import { ScheduleTargetInput } from '@aws-cdk/aws-scheduler-alpha/lib/input';
import { LambdaInvoke } from '@aws-cdk/aws-scheduler-targets-alpha';
import * as cdk from 'aws-cdk-lib';
import { Fn } from 'aws-cdk-lib';
import { Function } from 'aws-cdk-lib/aws-lambda';
import { Construct } from 'constructs';
export class BugReportStack extends cdk.Stack {
constructor(scope: Construct, id: string) {
super(scope, id, {
env: {
account: '123456789012',
region: 'us-east-2',
}
});
const functionArn = Fn.importValue("MyImportArn");
const lambda = Function.fromFunctionAttributes(this, "ImportedFunction", {
functionArn,
sameEnvironment: true,
});
const target = new LambdaInvoke(lambda, {
input: ScheduleTargetInput.fromObject({
foo: "bar"
}),
});
new Schedule(this, "Schedule", {
schedule: ScheduleExpression.rate(cdk.Duration.minutes(5)),
target,
});
}
}Possible Solution
If sameEnvironment is set to true on the imported lambda, the validations should be skipped.
