Importing aws:lambda:/function:Function resource inputs failed to validate

[sandervb2]

What happened?

When I try to import an aws:lambda/function:Function resource I receive warnings that one of 'filename, image_uri or s3_bucket' values must be set for 'S3Bucket, imageUri or code'. The resource does import succesfully and gives me the output code for it but execution fails with the following errors:

error: aws:lambda/function:Function resource '<my_lambda_function>' has a problem: Invalid combination of arguments. "s3_bucket": one of `filename,image_uri,s3_bucket` must be specified. Examine values at '<my_lambda_function>.s3Bucket'.
error: aws:lambda/function:Function resource '<my_lambda_function>' has a problem: Invalid combination of arguments. "image_uri": one of `filename,image_uri,s3_bucket` must be specified. Examine values at '<my_lambda_function>.imageUri'.
error: aws:lambda/function:Function resource '<my_lambda_function>' has a problem: Invalid combination of arguments. "filename": one of `filename,image_uri,s3_bucket` must be specified. Examine values at '<my_lambda_function>.code'.

Example

This is the output when I import the Lambda Function resource:

pulumi import aws:lambda/function:Function <my_lambda_function> <my_lambda_function>

Do you want to perform this import? yes

And this is the output when I try to execute the code using a 'pulumi preview':

@sandervb2 Thank you for reporting this issue and sorry for the trouble.

I suppose there is a problem somewhere in our Read implementation - either because we renamed the original property "filename" to "code", or because its type is Archive.

To unblock yourself, you probably need to specify the code property of your Function in the snippet that Pulumi generated.

Actually, it looks like we are already tracking the same issue in #2392. I'll close this new issue as duplicate, let's track it in there.
