  const buildRequest = (url) => ({

  contentType: "application/json",
  secure: import.meta.env.VITE_SECURE_OAUTH === 'true',
});

Hi, I will remove the secure prop - to support local dev the ${import.meta.env.VITE_JWT_TOKEN} is compiled to Bearer {{setting.token}} when in prod and is substituted with an actual token locally.  As I say, the app works fine the first time it is installed (so the token is correctly substituted for at least some of the time).

Just as a follow up - this is a chunk of the minified code showing the placeholder being inserted.

{Authorization:"Bearer {{setting.token}}"},contentType:"application/json",secure:!0}),g=(s,t)=>{const[a,r]=x.useState(!0),[l,c]=x.useState(null),[n,i]=x.useState(null);x.useEffect(()=>{d()},[s]);const d=async()=>{try{r(!0);const o=await t.request(v(s));i(o),c(null)}catch(o){o.status===401?c("Please ask a Zendesk administrator to re-authenticate with Auth0"):

I have tried setting the secure property to false within the Oauth property - as expected this fails with invalid token as the substitution is not made.

Hi - I have successfully authenticated using the bearer token at 2025-03-24T11:12:00, I will wait until the token expires and let you know the timestamp when I get the failure message. Kind regards Andy

Hi, at 2025-03-24T15:54:22 the API returned Proxy error: {:code=>"UnprocessableEntity", :status=>"422", :title=>"Unprocessable Entity", :message=>"Failed to get installation and oauth information for app."} when hitting https://problemsharedengineeringhelp.zendesk.com/proxy/v2/apps/secure
 

Hi Chris, Can you check the logs for our issue - we are using OAuth. Regards Andy

I will take a look at the docs and see if the offline_access is also required for Auth0

Hi  Chris,  Can I confirm that you are able to look at the logs to help us pinpoint our issue.  The issue that Parth Patel raised is different to ours.  I can confirm that we have tried all of the steps that Jerry has posted above.  We have also added the additional scope of offline_access.  Our integration is Auth0.  Again, it is working as expected once the app is installed, but we see the  422 error at a point where we think the token way not refresh (although I cant confirm unless someone can look at the logs).  Again, an example timestamp would be 2025-03-24T15:54:22.  We also saw the issue again this morning.  Reinstalling the app fixes the issue temporarily.
