[Bug]: aws_bedrockagent_agent "instruction" attribute validator max should be changed from 4000 to 8000

[jsermersheim-hv]

Terraform Core Version

1.6.6

AWS Provider Version

5.76.0

Affected Resource(s)

validation currently throws the following error for instruction lengths greater than 4000. "Attribute instruction string length must be between 40 and 4000, got: 4036"

Amazon increased the agent instruction limit to 8000 characters. The validator needs to be updated.

While the above screenshot shows the AWS Service Quota indicating 8000 characters, the AWS API reference documentation seems to lag behind at 4000 characters:

https://docs.aws.amazon.com/bedrock/latest/APIReference/API_agent_CreateAgent.html#bedrock-agent_CreateAgent-request-instruction

Here's the specific code block:

https://github.com/acwwat/terraform-provider-aws/blob/main/internal/service/bedrockagent/agent.go#L127-L135

Expected Behavior

The validator should allow up to 8000 characters

Actual Behavior

validation currently throws the following error for instruction lengths greater than 4000. "Attribute instruction string length must be between 40 and 4000, got: 4036"

Hi @jsermersheim-hv,

thanks for bringing this to our attention! I checked the service quotas on my end and you are right.

{
    "Quota": {
        "ServiceCode": "bedrock",
        "ServiceName": "Amazon Bedrock",
        "QuotaArn": "arn:aws:servicequotas:eu-central-1:464678460130:bedrock/L-6E3CDA2D",
        "QuotaCode": "L-6E3CDA2D",
        "QuotaName": "Characters in Agent instructions",
        "Value": 8000.0,
        "Unit": "None",
        "Adjustable": true,
        "GlobalQuota": false,
        "QuotaAppliedAtLevel": "ACCOUNT"
    }
}

Let me try to update the code base.
