I have a serverless.yml which contains definition and deployment for multiple lambdas and also the corresponding api gateway. However, I cannot get the log and log level to be applied to the lambda.
The below is added so that the log config. can be applied to all the lambdas, but it didn’t work.
```auto
provider:
name: aws
lambdaHashingVersion: 20201221
apiGateway:
minimumCompressionSize: 1024
runtime: nodejs16.x
memorySize: 512 # in MB, default is 1024
timeout: 10 # in seconds, default is 6
logRetentionInDays: ${file(./serverless_properties.yml):${self:provider.stage}.LOG_RETENTION_DAYS, "90"}
logs:
lambda:
logFormat: JSON
applicationLogLevel: ERROR
systemLogLevel: INFO
httpApi:
format: '{"request_id": "$context.requestId", "ip": "$context.identity.sourceIp", "requestTime":"$context.requestTime", "routeKey":"$context.routeKey", "status":"$context.status", "auth_error": "$context.authorizer.error", "error": "$context.error.message", "caller": "$context.identity.caller", "user": "$context.identity.user", "integration_error": "$context.integration.error" }'
```
I also tried the following; To configure the log level and stuff for a particular function, and it didn’t work as well.
```auto
functions:
get_releases_test_auth:
handler: main.GetReleases
events:
- httpApi:
method: get
path: "/test_auth/releases"
authorizer:
name: azure_ad_auth
logs:
# The Log Format to be used for all lambda functions (default: Text)
logFormat: JSON
# The Application Log Level to be used, This can only be set if `logFormat` is set to `JSON`
applicationLogLevel: ERROR
# The System Log Level to be used, This can only be set if `logFormat` is set to `JSON`
systemLogLevel: INFO
```
My framework version is defined as frameworkVersion: ^2.35.0 which I don’t think would be an issue, any help is really appreciated.

Hello, I’ve had the same issue using version 3.7 This feature appears to be broken in every version before major version 4.
What helped in my case was a plugin found here: [serverless-logging-config/README.md at main · theburningmonk/serverless-logging-config · GitHub](https://github.com/theburningmonk/serverless-logging-config/blob/main/README.md)
Hope it could help in your case as well
