How to turn off warnings during eventbridge deploy

[cm-yoshikikasama]

I get a warning every time I cdk deploy with the following implementation: stepfunctions are on the same stack and are defined as constructors, not cross stacks.
If the env is not specified in app.ts, there is no warning in the deploy command. Why do warnings appear when I specify the env, but not when I delete the env specification? If anyone knows how to solve this problem, I would appreciate your help.

app.ts

new ETLStack(app, `ETL${envKey.toUpperCase()}`, {
  description: `${parameter.projectName}-${parameter.envName}-test-tag`,
  env: {
    account: process.env.CDK_DEFAULT_ACCOUNT,
    region: process.env.CDK_DEFAULT_REGION,
  },

  
  tags: {
    Repository: `${parameter.projectName}-${parameter.envName}-test-tag`,
    Environment: parameter.envName,
  },

  projectName: parameter.projectName,
  envName: parameter.envName,
});

eventbridge.ts

import { Construct } from "constructs";
import * as events from "aws-cdk-lib/aws-events";
import * as eventsTargets from "aws-cdk-lib/aws-events-targets";
import * as sfn from "aws-cdk-lib/aws-stepfunctions";
import * as iam from "aws-cdk-lib/aws-iam";

export interface EventBridgeConstructProps {
  envName: string;
  projectName: string;
  dataSourceBucketName: string;
  stateMachineArn: string;
}

export class EventBridgeConstruct extends Construct {
  constructor(scope: Construct, id: string, props: EventBridgeConstructProps) {
    super(scope, id);
    const s3PutRule = new events.Rule(this, "S3PutRule", {
      eventPattern: {
        source: ["aws.s3"],
        detailType: ["Object Created"],
        detail: {
          bucket: {
            name: [props.dataSourceBucketName],
          },
          object: {
            key: [{ prefix: "input/" }],
            size: [{ numeric: [">", 0] }],
          },
        },
      },
      ruleName: `${props.projectName}-${props.envName}-etl-s3-put-rule`,
    });
    
    const eventBridgeExecutionRole = new iam.Role(
      this,
      `EventBridgeExecutionRole`,
      {
        assumedBy: new iam.ServicePrincipal("events.amazonaws.com"), 
        description:
          "An IAM role for EventBridge to Start Step Functions Execution",
        roleName: `EventBridgeExecutionRoleForStepFunctions-${props.envName}`,
      }
    );

    eventBridgeExecutionRole.addToPolicy(
      new iam.PolicyStatement({
        actions: ["states:StartExecution"], 
        resources: [props.stateMachineArn], 
      })
    );
    const stateMachine = sfn.StateMachine.fromStateMachineArn(
      this,
      "ImportedStateMachine",
      props.stateMachineArn
    );
    s3PutRule.addTarget(
      new eventsTargets.SfnStateMachine(stateMachine, {
        role: eventBridgeExecutionRole,
      })
    );
  }
}

npx cdk deploy --all

[Warning at /ETLDEV/EventBridge/S3PutRule] Either the Event Rule or target has an unresolved environment. If they are being used in a cross-environment setup you need to specify the environment for both. [ack: @aws-cdk/aws-events:ruleUnresolvedEnvironment]
