How to fix this waring ,

Argument of type "dict[str, str | int]" cannot be assigned to parameter "variables" of type "Input[Mapping[str, Input[str]]] | None" in function "__init__"
  Type "dict[str, str | int]" cannot be assigned to type "Input[Mapping[str, Input[str]]] | None"
    "dict[str, str | int]" is incompatible with "Mapping[str, Input[str]]"
      TypeVar "_VT_co@Mapping" is covariant
        Type "str | int" cannot be assigned to type "Input[str]"
          Type "int" cannot be assigned to type "Input[str]"
    "dict[str, str | int]" is incompatible with protocol "Awaitable[Mapping[str, Input[str]]]"
      "__await__" is not present
    "dict[str, str | int]" is incompatible with "Output[Mapping[str, Input[str]]]"

This is my code :


aws.lambda_.FunctionEnvironmentArgs(
            variables={
                "DESTN_BUCKET": s3_zip_log_bucket_name,
                "RDS_HOSTNAME": "<http://xxxx.ap-east-1.rds.amazonaws.com|xxxx.ap-east-1.rds.amazonaws.com>",
                "RDS_USERNAME": "admin",
                "RDS_PASSWORD": db_password,
                "RDS_PORT": "3306",
                "TTL": 172800,
            },
        ),

I think is need to do that to make dict convert to Input， But I don't know　to do

Hi there — have a look at this example. It looks similar to your code, so might help: https://github.com/pulumi/examples/blob/258d3bad0a00020704743e37911c51be63c06bb4/aws-py-serverless-raw/__main__.py#L73-L89

Hi, @miniature-musician-31262 Thank you for your reply, I can understand this code why not warring. https://github.com/pulumi/examples/blob/258d3bad0a00020704743e37911c51be63c06bb4/aws-py-serverless-raw/__main__.py#L73-L89. But for your code.

some_dict = {
  "THING": "one",
  "OTHER_THING": 2,
}

fn = aws.lambda_.Function("fn",
    runtime="python3.9",
    handler="handler.handler",
    role=role.arn,
    code=pulumi.FileArchive("./function"),
    environment=aws.lambda_.FunctionEnvironmentArgs(
        variables=some_dict,
    ))

I can not understand, It looks like my codes, but it works! Just eluded pylance’s inspection?

In general you shouldn’t have to manually cast anything from a string to an input of string, as plain strings are also valid inputs. Where are your

s3_zip_log_bucket_name

and

db_password

values coming from, though? Are they plain strings, or outputs of some other resource?

The warning is easy to fix: make sure the values are strings

...
                "RDS_PORT": "3306",
                "TTL": "172800",
...

these will be env vars anyway, so they will be strings.

@miniature-musician-31262 Thanks for reminding me! The

s3_zip_log_bucket_name

and

db_password

values are string too, I find the key is

"TTL": 172800

When I remove this line, It is fine.

There are no stupid questions 🙂
