Undefined variable

[okay-scam]

No matter what I do, I can't get the pdf to render using Gotenberg.

The PDF only ever renders with Failed to render HTML. Error: Undefined variable $username

My template <h2>Hello {{ $username }}</h2>

Default variables

{
  "username": "username_missing"
}

cURL

curl --request POST \
  --url http://localhost:8888/api/v1/document-templates/9d4186c0-4bd0-4732-8fb0-2944132d31b1/pdfs \
  --header 'content-type: application/json' \
  --data '{
  "variables": {
    "username": "sam.n",
  }
}'

it works for me, you have to fix your post request (no comma after "sam.n")

curl --request POST \
  --url http://localhost:8888/api/v1/document-templates/9d4186c0-4bd0-4732-8fb0-2944132d31b1/pdfs \
  --header 'content-type: application/json' \
  --data '{
  "variables": {
    "username": "sam.n"
  }
}'
