Discussion on: Build a RESTful API with the Serverless Framework

[Mubina Shaikh]

Hi, Sagar, i was trying to implement Nodejs App with Mysql to build it serverless following your article, i get this error.

Serverless: Configuration warning at 'provider.runtime': should be equal to one of the allowed values [dotnetcore2.1, dotnetcore3.1, go1.x, java11, java8, java8.al2, nodejs10.x, nodejs12.x, provided, provided.al2, python2.7, python3.6, python3.7, python3.8, ruby2.5, ruby2.7]

i use below versions
Angular:- 10.1.2
Node:- 12.18.0
Mysql:- 8.0.17

please help me with the above error, i have followed same steps as mentioned in your article. (excepts for db config password)

basically, you need to provide runtime in the serverless.yml file.

# serverless.yml
service: pokemon-service

provider:
  name: aws
  runtime: nodejs12.x // <-- here provide runtime
  stage: dev
  region: us-east-1
  memorySize: 512

Hi Sagar,

Thank you for sharing, upon changing serverless.yml runtime to nodejs12.x, i am not getting the error i mentioned in previous comment.

I am attaching screenshots of calling API in postman i dont get response as shown in your article, and get pokemon by id API doesnt work at all.

Please let me knoew how to get data of API correctly.

Also, I tried to debug by putting console statements in index.js file API's but console statements are not printed in BE.

app.get('/pokemon/', (req, res) => {
const query = 'SELECT * FROM pokemon_tb'
pool.query(query, (err, results, fields) => {
if (err) {
const response = { data: null, message: err.message, }
console.log('***********', response);
res.send(response)
}

    const pokemons = [...results]
    const response = {
        data: pokemons,
        message: 'All pokemons successfully retrieved.',
    }
    res.send(response)
})

})

please tell me why ?

[Sagar]

IDK exact reason behind this. you need crosscheck function with the article mention code blocks and also you've to debug the root cause of this.

Hi, i had crossed checked function code blocks with article code blocks, its the same.
Can please tell me why console statements arent printing, it should print right ?
