VistasGithub action assign a variable of type env an array of strings
I am having the following problem what you see in the image.
I have a.js file which returns me an array of url strings.
Then I should assign this array to an env variable as seen in the example below, but I get the following error.
You can tell me where I'm wrong.
on:
workflow_dispatch:
name: Test Download Multifile
jobs:
build:
name: Build
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
name: Check out current commit
- name: Url
run: |
URL=$(node ./actionMultifile.js)
echo $URL
echo "URL=$URL" >> $GITHUB_ENV
actionMultifile.js
async function getData(){
const url = [
"https://upload.wikimedia.org/wikipedia/commons/thumb/c/c9/Tyrannosaurus_rex_Sue_at_FMNH.jpg/440px-Tyrannosaurus_rex_Sue_at_FMNH.jpg",
"https://upload.wikimedia.org/wikipedia/commons/thumb/b/bc/Mosasaurus_beaugei_34.JPG/440px-Mosasaurus_beaugei_34.JPG"
]
return url;
}
getData().then((url) => {
console.log(url);
});

The problem occurs because you need to set the URL env variable using multiline strings
This is because the URL variable here isn't saved like this:
['https://upload.wikimedia.org/wikipedia/commons/thumb/c/c9/Tyrannosaurus_rex_Sue_at_FMNH.jpg/440px-Tyrannosaurus_rex_Sue_at_FMNH.jpg', 'https://upload.wikimedia.org/wikipedia/commons/thumb/b/bc/Mosasaurus_beaugei_34.JPG/440px-Mosasaurus_beaugei_34.JPG']
But like this:
[
'https://upload.wikimedia.org/wikipedia/commons/thumb/c/c9/Tyrannosaurus_rex_Sue_at_FMNH.jpg/440px-Tyrannosaurus_rex_Sue_at_FMNH.jpg',
'https://upload.wikimedia.org/wikipedia/commons/thumb/b/bc/Mosasaurus_beaugei_34.JPG/440px-Mosasaurus_beaugei_34.JPG'
]
Therefore, you workflow should look like this:
steps:
- name: Checkout repository content
uses: actions/checkout@v2 # Checkout the repository content to github runner.
- name: Setup Node Version
uses: actions/setup-node@v2
with:
node-version: 14 # Install the node version needed
- name: set multiline env var
run: |
echo 'URL<<EOF' >> $GITHUB_ENV
node ./actionMultifile.js >> $GITHUB_ENV
echo 'EOF' >> $GITHUB_ENV
Then, be careful, you won't be able to use the ${{ env.URL }} variable directly, otherwise it will only print the first line ([) and break. You need to use it between quotes (").
For example:
- name: use env var
run: echo "${{ env.URL }}"
- name: use env var directly
run: echo "$URL"
I tested it here if you want to take a look:
