Hi Colin,
Would you be able to provide us a link to your repository? This will help us to debug the issue more effectively.
Thanks!

Hi, Please see below my Main.js and Iframe.html

event.preventDefault();

Thanks for sending this over, a couple questions and notes:
1. I see that you have the secure flag listed in the settings. Are you inputting the bearer token as a secure param?
2. Are you encountering this issue when testing the application locally or when zipped and installed in your instance as a private app?
3. The specification of charset=utf-8 on the contentType is redundant as the default for json is utf-8.
Thanks! -
Hi,
1: I've tried with the secure setting in a param file and receive the same error.
2: I receive the error when testing locally, I received a 500 error when installed as a private app.
3: Noted regarding the content type, thank you.

Hey Colin,
Would you mind if I move this into a ticket so that you can share your code with us?
Thanks!
-
Hi Eric, Certainly, thank you.
-
Hi,
I have the same issue, can you share with me the solution please?is it ok to open a ticket to solve it?
thank you.

Hi Pham! From my research, it appears that this may have been an issue with one of our integration services that has been resolved for a few weeks. Can you confirm that you are still experiencing this problem?
-
Hi I am receiving this error today in local dev mode I have added a secure token to my manifest like so
```
"parameters": [
{
"name": "token",
"type": "text",
"secure": true
}
] -
Hi Stuart,
If you're able to provide a link to the repo or code snippets that would be helpful for us to dig into it. It would also be greatly appreciated if you could provide context around when this error first began. Has it always been unsuccessful or have any known changes been made prior to it occurring?
Looking forward to your response!
Best,
Erica

Hello,
I'm experiencing this issue in a Zendesk support app where I need to use a third-party API requiring HTTP Basic authentication. The issue is so far only locally and I've not yet tried to install the app. The following is code that makes the request:
const metadata = await client.metadata();
const apiUrl = metadata.settings.apiUrl;
const settings = {
url: 'https://' + apiUrl + '/' + path + (queryParams ? '?' + queryParams : ''),
secure: true,
cors: false,
type: 'GET',
dataType: 'json',
contentType: 'application/json',
headers: {
Authorization: 'Basic {{setting.apiToken}}',
},
accepts: "application/json",
};
return client.request(settings)
.then(successHandler)
.catch(handleFailure);And this is how my `menifet.json` look like:
{This is not a new app. I'm changing the API endpoints in an existing app.
"name": "...",
"author": {
"name": "...",
"email": "...",
"url": "..."
},
"defaultLocale": "da",
"private": true,
"location": {
"support": {
"nav_bar": "assets/index.html"
}
},
"version": "0.9.12",
"frameworkVersion": "2.0",
"domainWhitelist": ["{{setting.apiUrl}}"],
"parameters": [
{
"name": "apiUrl",
"type": "url",
"required": true,
"secure": false,
"default": "..."
},
{
"name": "apiToken",
"type": "password",
"required": true,
"secure": true,
"default": "..."
}
]
}Best regards,Ismail -
Hi Ismail Faizi
Secure settings do not work locally. You will need to push the app to test them or add a separate insecure parameter to hold the token for insecure local testing. -
Thank you for your answer Ahmed Zaid. That is very unfortunate. Do you know whether there is a way to find out whether the app is running locally? Knowing so will allow me to make an "insecure" request locally and use secure settings when it is not local.
-
For anyone having this issue. The following is working both locally and when installed:
const metadata = await client.metadata();
const apiUrl = metadata.settings.apiUrl;
const settings = {
url: 'https://' + apiUrl + '/' + path + (queryParams ? '?' + queryParams : ''),
secure: !!metadata.installationId,
cors: false,
type: 'GET',
dataType: 'json',
contentType: 'application/json',
headers: {
Authorization: `Basic ${ !!metadata.installationId ? '{{setting.apiToken}}' : metadata.settings.apiToken }`,
},
accepts: "application/json",
};
return client.request(settings)
.then(successHandler)
.catch(handleFailure);The `installationId` will be `0` when the app is running locally.
-
I was really hoping this would work. But when I fetch client.metadata I get a uuid installationId when I run locally
So based on further testing and investigating,
when local - the value is a string
when installed - the value is a number
so we can use a typeof check to work out if we are running locally or installed.
-
Very interesting Sal. Are you using zat or zcli? I'm using zat and here the installationId is 0 locally.

Hi I'm having a lot of problems with this too. In my manifest I have:
```
{
"parameters": [
{
"name": "token",
"type": "oauth"
}
],
"oauth": {
"client_id": "XXX",
"client_secret": "XXX",
"authorize_uri": "https://XXX/oauth2/authorize",
"access_token_uri": "https://XXX/oauth2/token",
"scope": "email profile offline_access"
}}
```
and my code does
```
client.request({
url: 'https://xxx.com/some/endpoint',
type: 'GET',
secure: true,
headers: {Authorization: 'Bearer {{setting.token}}'},
})```
The app seems to authorise fine when I go through the process but I still get this proxy error.
One detail is that I've installed the app in a zendesk sandbox to test it. Is this expected to work?
-
@Ismail - I am using ZCLI.
@Will I think you are missing secure: true for the parameter in the manifest file
-
If I set that I get
Uploading app... Uploaded
Deploying app... Failed
› Error: Error: oauth parameter cannot be set to be secure. -
Hey Will,
You mind if we pull this into a ticket so that you can share a zip of your app for us to take a look at?
Thanks!
