I have this section in my main.wasp file: "head: [
"<meta name="viewport" content="minimum-scale=1, initial-scale=1, width=device-width" />", "<link rel="shortcut icon" href="/favicon.ico" type="image/x-icon" />", "<link rel="icon" href="/favicon.ico" type="image/x-icon" />", "<script src='https://js.stripe.com/v3/' />", "<script src='https://js.stripe.com/v3/pricing-table.js'></script>", "<stripe-pricing-table pricing-table-id='prctbl_1R6yHpQ3pz8nOT2l4854f2w1' publishable-key='pk_test_51Qrp2qQ3pz8nOT2laKRMYmvt5sRrXZjXNtDvNjDdgaX8BzFHon4z6thFxuR0ELGv5lZASVUdfEA5FyOcjqyfj1x500sau6o8yH'> </stripe-pricing-table>", ]" I am getting the following error: Parse error: Unexpected token: " Expected one of the following tokens instead: '(','[',']','{','import','true','false',<string>,<number>,<number>,'{=',<identifier> "<script src='https://js.stripe.com/v3/' />", "<script src='https://js.stripe.com/v3/pricing-table.js'></script>", What is the problem?

Hi @cmilazzo. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The problem is with the syntax in your head array. In Wasp, the head field expects an array of strings, but there's an issue with how your script tags are formatted. Looking at the error message, it seems that Wasp is having trouble parsing the quotes within your script tags. This is because in Wasp, strings need to be properly escaped when they contain quotes. According to the documentation, here's how you should format items in the head array:

app myApp {
  wasp: {
    version: "^0.13.0"
  },
  title: "My App",
  head: [
    "<link rel=\"stylesheet\" href=\"<https://fonts.googleapis.com/css?family=Roboto:300,400,500&display=swap\"> />",
    "<script src=\"<https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.9.3/Chart.min.js\"></script>",>
    "<meta name=\"viewport\" content=\"minimum-scale=1, initial-scale=1, width=device-width\" />"
  ]
}

app myApp {
  wasp: {
    version: "^0.13.0"
  },
  title: "My App",
  head: [
    "<link rel=\"stylesheet\" href=\"<https://fonts.googleapis.com/css?family=Roboto:300,400,500&display=swap\"> />",
    "<script src=\"<https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.9.3/Chart.min.js\"></script>",>
    "<meta name=\"viewport\" content=\"minimum-scale=1, initial-scale=1, width=device-width\" />"
  ]
}

Customizing the App Notice how the double quotes within the HTML tags are escaped with a backslash (\"). You need to do the same with your script tags, and you should use double quotes consistently throughout. Try changing your head section to use escaped double quotes instead of single quotes:

head: [
  "<meta name=\"viewport\" content=\"minimum-scale=1, initial-scale=1, width=device-width\" />",
  "<link rel=\"shortcut icon\" href=\"/favicon.ico\" type=\"image/x-icon\" />",
  "<link rel=\"icon\" href=\"/favicon.ico\" type=\"image/x-icon\" />",
  "<script src=\"<https://js.stripe.com/v3/\"></script>",>
  "<script src=\"<https://js.stripe.com/v3/pricing-table.js\"></script>",>
  "<stripe-pricing-table pricing-table-id=\"prctbl_1R6yHpQ3pz8nOT2l4854f2w1\" publishable-key=\"pk_test_51Qrp2qQ3pz8nOT2laKRMYmvt5sRrXZjXNtDvNjDdgaX8BzFHon4z6thFxuR0ELGv5lZASVUdfEA5FyOcjqyfj1x500sau6o8yH\"></stripe-pricing-table>"
]

head: [
  "<meta name=\"viewport\" content=\"minimum-scale=1, initial-scale=1, width=device-width\" />",
  "<link rel=\"shortcut icon\" href=\"/favicon.ico\" type=\"image/x-icon\" />",
  "<link rel=\"icon\" href=\"/favicon.ico\" type=\"image/x-icon\" />",
  "<script src=\"<https://js.stripe.com/v3/\"></script>",>
  "<script src=\"<https://js.stripe.com/v3/pricing-table.js\"></script>",>
  "<stripe-pricing-table pricing-table-id=\"prctbl_1R6yHpQ3pz8nOT2l4854f2w1\" publishable-key=\"pk_test_51Qrp2qQ3pz8nOT2laKRMYmvt5sRrXZjXNtDvNjDdgaX8BzFHon4z6thFxuR0ELGv5lZASVUdfEA5FyOcjqyfj1x500sau6o8yH\"></stripe-pricing-table>"
]

Also note that I've changed the self-closing script tag (<script ... />) to a standard opening and closing tag format (<script ...></script>), which is more widely supported. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @cmilazzo, I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist: Perhaps try again in 15mins?

Thanks @kapa.ai . Your solution was almost right, but it included some extra ">" at the end of the script lines.

Let me check the knowledge base for you again. One moment! :books: ---------------------- I apologize for the error in my solution. You're right that I included some extra closing brackets at the end of the script tags. Here's the corrected version of the head section with proper escaping and without the extra closing brackets:

head: [
  "<meta name=\"viewport\" content=\"minimum-scale=1, initial-scale=1, width=device-width\" />",
  "<link rel=\"shortcut icon\" href=\"/favicon.ico\" type=\"image/x-icon\" />",
  "<link rel=\"icon\" href=\"/favicon.ico\" type=\"image/x-icon\" />",
  "<script src=\"<https://js.stripe.com/v3/\"></script>",>
  "<script src=\"<https://js.stripe.com/v3/pricing-table.js\"></script>",>
  "<stripe-pricing-table pricing-table-id=\"prctbl_1R6yHpQ3pz8nOT2l4854f2w1\" publishable-key=\"pk_test_51Qrp2qQ3pz8nOT2laKRMYmvt5sRrXZjXNtDvNjDdgaX8BzFHon4z6thFxuR0ELGv5lZASVUdfEA5FyOcjqyfj1x500sau6o8yH\"></stripe-pricing-table>"
]

head: [
  "<meta name=\"viewport\" content=\"minimum-scale=1, initial-scale=1, width=device-width\" />",
  "<link rel=\"shortcut icon\" href=\"/favicon.ico\" type=\"image/x-icon\" />",
  "<link rel=\"icon\" href=\"/favicon.ico\" type=\"image/x-icon\" />",
  "<script src=\"<https://js.stripe.com/v3/\"></script>",>
  "<script src=\"<https://js.stripe.com/v3/pricing-table.js\"></script>",>
  "<stripe-pricing-table pricing-table-id=\"prctbl_1R6yHpQ3pz8nOT2l4854f2w1\" publishable-key=\"pk_test_51Qrp2qQ3pz8nOT2laKRMYmvt5sRrXZjXNtDvNjDdgaX8BzFHon4z6thFxuR0ELGv5lZASVUdfEA5FyOcjqyfj1x500sau6o8yH\"></stripe-pricing-table>"
]

Thank you for pointing out the mistake. The key is to use escaped double quotes within the HTML tags and ensure proper HTML syntax for the script tags. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @cmilazzo, I seem to be having a bit of trouble.
