write environment variable to JSON in pipelines.yml

Micha Roon_kp26hy

my `bitbucket-pipelines.yml` file contains the following lines:

default:
  - step:
caches:
        - node
script: 
        - echo "{\"infuraKey\": \"$INFURA_KEY\"}" > infura-key.json
        - npm i ganache-core
        - npm i
        - npm test

the line with `echo "...` generates a validation error. What is the correct syntax?

Hi Micha,

YAML parses the ': ' (colon immediately followed by a space) as a map. Which breaks the parsing we expect (a string).

To working around this, you can either

Place the entire command into a string:

default:
  - step:
caches:
        - node
script: 
        - 'echo "{\"infuraKey\": \"$INFURA_KEY\"}" > infura-key.json'
        - npm i ganache-core
        - npm i
        - npm test

Or, place the command onto a separate line:

default:
  - step:
caches:
        - node
script: 
        - |
echo "{\"infuraKey\": \"$INFURA_KEY\"}" > infura-key.json
        - npm i ganache-core
        - npm i
        - npm test

Thanks,

Phil
