Cannot import Jelastic Manifest with cURL command using two -H parameters - jelastic

Question

I'm trying to create a Jelastic Manifest with a cURL command inside it. When I import it, it gives me an error but unfortunately I have no access to the console (disabled by the provider).
The command is the following :
curl -X POST <my_url> -H "Content-Type: application/json" -H "Authorization: Bearer <token>" -d "{}"
Some additionnal information :
The URL is correct 100%
The token does not contain any special characters : Only upper/lowercase characters and numbers
The command is run successfully from the command line
If I remove the first -H parameter, I can import my manifest. Same if I remove the second -H parameter and keep the first one
My guess is that, somehow, having two -H is not considered as valid but I don't know why. Any ideas ?

The "two -H parameters" wasn't a root cause in your question.
The thing is that the YAML gets the data you sent as a key/value array (dictionary).
In your example it would be:
curl -s -X POST https://test.com -H "Content-Type - as a key,
and
application/json" -H "Authorization: Bearer xx" -d "{\"Key\":\"Value\"}" - as a value.
If you need an array of strings the YAML may be as this
cmd [cp]:
- 'curl -s -X POST https://test.com -H "Content-Type: application/json" -H "Authorization: Bearer xx" -d "{\"Key\":\"Value\"}"'
If you need a multi-line string it should look like this
cmd [cp]: |
curl -s -X POST https://test.com -H "Content-Type: application/json" -H "Authorization: Bearer xx" -d "{\"Key\":\"Value\"}"
