Question: multiple allow_origin entries

Question

I'm trying to pass in multiple allow_origin hostnames via .env file

.env:
CORS_ALLOW_ORIGIN='["http://localhost:3001","http://localhost:3002"]'

nelmio_cors.yaml
allow_origin: ['%env(json:CORS_ALLOW_ORIGIN)%']

but it keeps failing

when I do this in nelmio_cors.yaml, it works fine:
allow_origin: ['http://localhost:3001','http://localhost:3002']

Did anyone come across this? TIA 🙏

How could one pass in multiple entries to allow_origin from .env? I'm out of ideas, ChatGPT+ is out of ideas too...

Additional context

Even GPT-4o thinks this should work, but sadly it doesn't (explored different options with ChatGPT too 🫠)
