Using node.js on WSL2 with Debian, I'm doing a sample project as detailed here, and I'm currently at this stage.
OLD [solved; scroll to NEW]
When I try to deploy, it gives me
An error occurred: ApiGatewayResourceNotesId - Resource's path part only allow a-zA-Z0-9._- and curly braces at the beginning and the end. (Service: AmazonApiGateway; Status Code: 400; Error Code: BadRequestException;
It seems to be coming from my YAML line here (I say seems because this is the only code in all my project files which mentions "(R|r)esource")
(Error #1)
environment:
tableName: notes-sample
iamRoleStatements:
- Effect: Allow
Action:
- dynamodb:Scan
- dynamodb:Query
- dynamodb:GetItem
- dynamodb:PutItem
- dynamodb:UpdateItem
- dynamodb:DeleteItem
- dynamodb:DescribeTable
Resource: "arn:aws:dynamodb:us-west-2:*:*" # <-- here ---
Yet the example shown on the website uses the same format as above, and I assume it works for them.
Edit 1: Also using Resource: '*' gives the same error.
Edit 2: Also using Amazon's docs and formatting like Resource: "arn:aws:dynamodb:us-west-2::" gives the same error.
Edit 4: Also tried
Resource:
Fn::Join:
- ''
- - "arn:aws:dynamodb:us-west-2:<redacted>:table/notes-sample"
I've also tried formatting it this way
(Error #2)
environment:
tableName: { "Ref": "notes-sample" } # <-- here: change 1 ---
# 'iamRoleStatements' defines the permission policy for the Lambda function.
# In this case Lambda functions are granted with permissions to access DynamoDB.
iamRoleStatements:

Resource: { "Fn::GetAtt": ["sample-note", "Arn"] } # <-- here: change 2 ---
however, when Serverless validates the template, it gives me the error
Error: The CloudFormation template is invalid: Template format error: Unresolved resource dependencies [notes-sample] in the Resources block of the template
at /home/USER/.nvm/versions/node/v15.6.0/lib/node_modules/serverless/lib/plugins/aws/deploy/lib/validateTemplate.js:20:13
For one, I can't find that folder on my PC, and don't know where else it might be, and two the problem still seems to be this one line of code, and I don't know what I'm missing, here.
I've looked at examples one, two, and tried to go through this Japanese site, but I don't seem to be seeing what's wrong with this line.
I appreciate anyone's help.
Edit 3: Also using Resource: { arn:aws:dynamodb:us-west-2:: } or Resource: { arn:aws:dynamodb:us-west-2:*:* } gives this error
Error: The CloudFormation template is invalid: [/Resources/IamRoleLambdaExecution/Type/Policies/0/PolicyDocument/Statement/2/Resource/arn:aws:dynamodb:us-west-2:*:*] 'null' values are not allowed in templates
I found out I was focusing on the wrong area and for two of my YAML files function definitions I had used [brackets] in place of {braces} from
update:
handler: update.main
events:
- http:
path: notes/[id] # <-- here --
method: put
delete:
handler: delete.main
events:
- http:
path: notes/[id] # <-- here --
method: delete
to
update:
handler: update.main
events:
- http:
path: notes/{id} # <-- here --
method: put
delete:
handler: delete.main
events:
- http:
path: notes/{id} # <-- here --
method: delete
Edit 5: I also fixed all the functions using path: notes to path: notes-sample so they match my [environment][tableName] declaration.
NEW
However, now the error I'm getting is
An error occurred: DeleteLambdaFunction - Uploaded file must be a non-empty zip (Service: AWSLambdaInternal; Status Code: 400; Error Code: InvalidParameterValueException
I checked out AWS Lambda deployment guide and this Python thread, neither of which helped directly solve this.
