Error "found unhashable key" while trying to read a yaml file

Question

I am trying to read .yaml file but getting "found unhashable key" error. Sample code and .yaml is mentioned below for reference

test.py

file_path = "test.yaml"
try:
    with open(file_path) as file:
        res = yaml.safe_load(file)
except Exception as e:
    print("e",e)

test.yaml

jobs:
- job: CLEANUP
  connection:
    dbms: mysql
    user: {{username}}

If you're running into this problem with helm templates, consider just [excluding these files](https://github.com/pre-commit/pre-commit-hooks/issues/420). — Jesse, Apr 05 '22 at 17:52

Cant change the .yaml file – Ashutosh gupta Aug 07 '20 at 08:53
Otherwise you have to do some string parsing based on the input format to get it done – MukeshRKrish Aug 07 '20 at 14:12

Isn't it because of {{username}}? All built-in immutable types are hashable, but mutable ones are not, so hashable types include all numbers, strings (both unicode and bytes) and tuple. Common unhashable types include list, dict and set, and {{username}} is dict syntax.
