• NextJS: Error serializing `.data.data` returned from `getServerSideProps`

  I'm new to NextJS. I'm working on a simple page in which I need to retrieve data from my backend app. My backend app is a totally separate app written in go. My undestanding is that I must use getServerSideProps to get data from the server on load, so I've got the following:

  myProject/pages/category/new.js:

  export default function AddNewCategory(data) {
  ...
  }
  
  export const getServerSideProps = async () => {
      const data = await getAllCategories();
      console.log(await data)
      return {
          props: {
              data: { data }
          }
      };
  };
  

  myProject/api/category.js:

  import axios from "axios";
  
  // getAllCategories returns a list of all active categories
  export const getAllCategories = async() => {
  
      axios.get("http://127.0.0.1:8080/api/v1/categories")
          .then(function (response) {
              console.log(response.data)
              return response.data;
          })
          .catch(error => {
              console.error("error")
              console.log(error)
          })
  
  }
  

  As you can see I've got a print statement in getAllCategories which prints:

  {
    data: [
      {
        id: 1,
        name: 'Pop',
        slug: 'pop',
        description: 'Pop',
        parent: 0,
        active: true,
        created_at: '2022-05-03T19:50:00-04:00',
        updated_at: '2022-05-03T19:50:00-04:00',
        deleted_at: null
      },
      {
        id: 3,
        name: 'Pop 2',
        slug: 'pop-2',
        description: 'Pop',
        parent: 0,
        active: true,
        created_at: '2022-05-03T19:50:24-04:00',
        updated_at: '2022-05-03T19:50:24-04:00',
        deleted_at: null
      }
    ]
  }
  

  yet I'm getting the following error:

  error - Error: Error serializing .data.data returned from getServerSideProps in "/category/new". Reason: undefined cannot be serialized as JSON. Please use null or omit this value.

  I saw around that I should try to convert the data to string and then back to json:

  return { 
    props: { 
      data: JSON.parse(JSON.stringify(data)) 
    } 
  };
  

  but when I do this I'm getting a different error:

  error - SyntaxError: Unexpected token u in JSON at position 0

  I'm using next@12.1.5

  Any idea what's going on?
• jq: error (at <stdin>:1): null (null) cannot be matched, as it is not a string

  $ jq '.y | gsub(","; "-")' <<< '{"y": "a,b"}'
  "a-b"
  $ jq '.y | gsub(","; "-")' <<< '{"x": "a"}'
  jq: error (at <stdin>:1): null (null) cannot be matched, as it is not a string
  

  I got the above error. I can use if-else-end statement to solve the problem. But it is a little verbose.

  What is the most succinct way to fix the error so that .y is still accessed with "," replaced by "-", but when .y does not exist, an empty string will be printed?
• creating a nested json output file using jq variables using

  I'm trying to create a json file via shellscript, and someone has mentioned jq, but I'm struggling a little bit to make it work: The desire output is:

  inboundurls{
    "op": "add",
    "path": "/support",
    "apiSupports": [
      {
        "familyType": "EXAMPLE",
        "healthCheckUris": "http://example.com"
      }
    ],
    "inboundurls": [
      {
        "healthCheckUris": "http://example.com"
      }
    ]
  }
  

  Researching about I found a start point, but it's not working properly, I need some help, here is what I have:

  script:

  #!/bin/bash
  apiSupports=$(jq -n --arg familyType EXAMPLE \
                --arg healthCheckUris http://example.com \
                '$ARGS.named'
  )
  
  final=$(jq -n --arg op "add" \
                --arg path "/supportServices" \
                --argjson apiSupports "[$apiSupports]" \
                '$ARGS.named'
  )
  echo "$final"
  

  the output of the script above:

  {
    "op": "add",
    "path": "/supportServices",
    "apiSupports": [
      {
        "familyType": "EXAMPLE",
        "healthCheckUris": "http://example.com"
      }
    ]
  }
  

  If anyone could help me I would be glad, or even suggesting Ideas, thank you in advance?
