Script command using ":" causing error in .gitlab-ci.yml execution

Question

Below my .gitlab-ci.yml file:

image: docker:latest

services:
    - docker:dind

stages:
    - deploy_dev_env

Deploy DEV Environment:

    stage: deploy_dev_env

    script:

        - curl -v -H "Content-Type: multipart/form-data" -X PUT -F uploadInput=@schema/schema.xml -F overwrite=true -F xmlaEnabledFlag=true -F parameters="DataSource=outputDS" -F parameters="EnableXmla=true" -u $PENTAHO_DEPLOY_USER:$PENTAHO_DEPLOY_PASSWORD http://$PENTAHO_HOST/pentaho/plugin/data-access/api/datasource/analysis/catalog/sca

This very simple script is causing an error because the colons(:) in the "Content-Type: multipart/form-data" piece.

Running the CI Lint in the script I get the following:

Status: syntax is incorrect

jobs:deploy dev environment:script config should be a string or an array containing strings and arrays of strings

If I replace "Content-Type: multipart/form-data" by "Content-Type multipart/form-data" (removed the ":"), I get I correct syntax for my .gitlab-ci.yml file.

Is this a bug or should I re-write my curl command in a different way ?

Docs warn about special characters in yaml script:

Note: Sometimes, script commands will need to be wrapped in single or double quotes. For example, commands that contain a colon (:) need to be wrapped in quotes so that the YAML parser knows to interpret the whole thing as a string rather than a “key: value” pair. Be careful when using special characters: :, {, }, [, ], ,, &, *, #, ?, |, -, <, >, =, !, %, @, `.

One of the option would be to use yaml block scalar

Deploy DEV Environment:
    stage: deploy_dev_env
    script: >
        curl -v -H "Content-Type: multipart/form-data" -X PUT -F uploadInput=@schema/schema.xml -F overwrite=true -F xmlaEnabledFlag=true -F parameters="DataSource=outputDS" -F parameters="EnableXmla=true" -u $PENTAHO_DEPLOY_USER:$PENTAHO_DEPLOY_PASSWORD http://$PENTAHO_HOST/pentaho/plugin/data-access/api/datasource/analysis/catalog/sca

or use some other way to escape colon in yaml.
