cli: Netlify CLI deploy command error when deploying golang binary : Invalid AWS Lambda parameters. Reserved keys used in this request

Hi, i want to try netlify to host my golang project. I clone the hello world project from here https://github.com/netlify/aws-lambda-go-example and have installed netlify via npm install netlify-cli -g. The netlify build command had run successfully and the binary is created under functions folder. The problem happens when i run netlify deploy --prod and it gives me this error (took with DEBUG on):

i already tried googling with Invalid AWS Lambda parameters. Reserved keys used in this request keyword and stumbled upon this thread : https://community.netlify.com/t/build-fails-invalid-aws-lambda-parameters/4235/3 and the case is almost similar. The difference is the solution mentioned that

the restriction of the maximum size of environment variables concatenated all together (e.g. VAR1=val1,VAR2=val2) should not be bigger than 4,096 bytes.

but it confuses me more since i have no environment variables to begin with since this is a hello world project. I also take a look at the reserved environment variable at https://docs.aws.amazon.com/lambda/latest/dg/configuration-envvars.html#configuration-envvars-runtime but found that my environment variables is not conflicted with the one mentioned in AWS documentation.

My question is: If netlify deploy takes into account my local environment variable size so it violates the 4096 rules, what is the workaround to deploy my functions and site to netlify using netlify cli ? i know there are ways such using trigger from git commits but i want to stick with netlify deploy command if it’s possible. I also read in documentation that it should be run without problem : https://cli.netlify.com/commands/deploy

Thanks in advance!

PS: i’m using go mod and here is my Makefile

build:
	GO111MODULE="on"
	mkdir -p functions
	go get ./...
	go build -o functions/hello-lambda ./...
