Trouble Importing Lambda Function with Terraform's New Import Block

[ankitaameenaa]

Terraform Version

Terraform v1.6.2
on windows_amd64
+ provider registry.terraform.io/hashicorp/aws v5.22.0

Terraform Configuration Files

import {
id = "xxxxxx"
to = aws_lambda_function.xxxxxx
}

Debug Output

will provide if needed

Expected Behavior

Should be able to create generated.tf

Actual Behavior

Error: Invalid combination of arguments

with aws_lambda_function.DeviceUsageJob,
on generated.tf line 16:
(source code not available)

"s3_bucket": one of filename,image_uri,s3_bucket must be specified

Steps to Reproduce

terraform init
terraform plan -generate-config-out=generated.tf

Additional Context

It is generating a 'generated.tf' file in which, for some Lambda functions, the creation configuration includes 's3_bucket' without specifying one of filename, image_uri, or s3_bucket. However, for some other Lambda functions, it does not generate the configuration and gives an error stating that 's3_bucket' must be specified as one of filename, image_uri, or `s3_bucket."

Hi @ankitaameenaa,

The error here is again from the provider, not from Terraform itself. The state returned by the provider for the aws_lambda_function resource appears to be missing values which would be required if it were written in the configuration. Since Terraform cannot guess what these values should be, it is up to the provider to return them in the read state. While the resource implementation would need to be changed in the provider to allow for config generation, the normal import process should work as expected if you create a resource block for the aws_lambda_function manually.

Thanks!
