Having trouble debugging your code? Can't see the data that's supposed to be there? Here is a list of things you probably want to check first:

Given that you are working in a Docker/cloud environment:

1. Dockerfile

2. Docker-compose file

   1. variable names

   2. container names

   3. endpoints

3. Docker containers

   1. variable values

   2. logs

4. Database

   1. DB status: is your DB running?

   2. data status: is your data there? Are they seeded correctly?

   3. data referencing:

      1. Are the values updated?

         • If your code needs to fetch data using sql statements that refer to multiple attributes, check if:

           • all the attribute names are correct

           • all the values referred to are correct AND up-to-date (some values might be regularly updated or changed) - for example, your gitpod workspace' IP address.

5. Your code

   1. Typo, misspellings

   2. return is actually returning something

   3. Datatype

      1. When your codes pass around data, see if:

         1. Input & Output data have the expected data structures

         2. Data returned by return statement has the expected data structure
