The policy document was incorrect for the case when guardrailIdentifier is an ARN, so I added a condition to address this.

policyStatements.push(
new iam.PolicyStatement({
actions: ['bedrock:ApplyGuardrail'],
resources: [
Stack.of(this).formatArn({
service: 'bedrock',
resource: 'guardrail',
resourceName: this.props.guardrail.guardrailIdentifier,
}),
isArn
? this.props.guardrail.guardrailIdentifier
: Stack.of(this).formatArn({
service: 'bedrock',
resource: 'guardrail',
resourceName: this.props.guardrail.guardrailIdentifier,
}),
],
}),
);
