Each time I attempt to deploy to Firebase Function I receive an error that says, "Error: An unexpected error has occurred." I have reached out to firebase support, but have not received a response as of yet. Curious, has anyone else seen this? I was able to find this in the logs in firebase.

Unable to retrieve the repository metadata for projects/restored-temecula-mobile-app/locations/us-central1/repositories/gcf-artifacts. Ensure that the Cloud Functions service account has 'artifactregistry.repositories.list' and 'artifactregistry.repositories.get' permissions. You can add the permissions by granting the role 'roles/artifactregistry.reader'.

Hello,
I followed all the steps for firebase on your readme, but Im still getting a cors error.
"Access to fetch at 'xyz' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled."
Can you please help me with this?

Do you know how to solve this please?

Hi, I was trying to test your firebase URL. But, I an getting error 504 with the server. I used before the repo from CORS Anywhere getting temporary access to his server and works fine, and I created my own in firebase but didn't work either. So, just to be sure, If I prepend your URL to the APIs URL, the server should be making the request to the correct URL (the APIs one)?? I am sorry if I sound like a caveman (I am still learning english). I am using Axios to make the request (not fetch), could be this a problem with the server? Please help me a little... Thanks

Each time I attempt to send a HTTP POST request to my Firebase Function, I receive an error in my browser console, a status 503 error.

I am attempting the post request from a squarespace website in chrome browser. I am sending the exact same information that was sent when using Heroku as 'middleware' for the POST requests from this page. It is a very basic JSON string. Example below.

{ "to": ["ExponentPushToken[dhLJeWNqW61r1ZBUkAwOtA]"], "title": "Hello World! ", "body": "I am Mark Logue, and I made this app!", "sound": "default", "data": {"event": ""} }

The website I am sending the post request from is on my cors-anywhere whitelist with the index.js file.

There are two concerning logs that I found within the Firebase Function (Google Cloud) logs for this function. First when I look at the log for the POST request, it shows in initial Options status of 204, see the log below:

{ "insertId": "6372a16400076996e307afbc", "httpRequest": { "requestMethod": "OPTIONS", "requestUrl": "https://proxy-hwp6dcya3a-uc.a.run.app/https://exp.host/--/api/v2/push/send", "requestSize": "761", "status": 204, "responseSize": "863", "userAgent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36", "remoteIp": "47.149.74.45", "referer": "https://restoredtemecula.church/", "serverIp": "216.239.36.53", "latency": "1.341490290s", "protocol": "HTTP/1.1" }, "resource": { "type": "cloud_run_revision", "labels": { "configuration_name": "proxy", "location": "us-central1", "revision_name": "proxy-hvnfg", "service_name": "proxy", "project_id": "restored-temecula-mobile-app" } }, "timestamp": "2022-11-14T20:13:24.485782Z", "severity": "INFO", "labels": { "instanceId": "0074e2ccb212737e5aad036cd3cebcfe4d5f35f47d168e939180e59572278e50b0cb6b75be2da34e4a6c16bbab33905987e3d9640d703e97d54f9708a58c14dc9f29", "goog-managed-by": "cloudfunctions" }, "logName": "projects/restored-temecula-mobile-app/logs/run.googleapis.com%2Frequests", "trace": "projects/restored-temecula-mobile-app/traces/ca1ce4c9d9432e0ab47d756bff0cf16c", "receiveTimestamp": "2022-11-14T20:13:24.492659539Z", "spanId": "14113124528369450882", "traceSampled": true }

Second, I receive in the 503 status error both in the logs in firebase function (google cloud) and in my chrome browser (logging the server response for the POST request). Here is the firebase funciton/google cloud log for the 503 status:

{ "insertId": "6372a177000a1e8dbb2702ed", "httpRequest": { "requestMethod": "POST", "requestUrl": "https://proxy-hwp6dcya3a-uc.a.run.app/https://exp.host/--/api/v2/push/send", "requestSize": "1171", "status": 503, "responseSize": "1201", "userAgent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36", "remoteIp": "47.149.74.45", "referer": "https://restoredtemecula.church/", "serverIp": "216.239.36.53", "latency": "19.114303071s", "protocol": "HTTP/1.1" }, "resource": { "type": "cloud_run_revision", "labels": { "location": "us-central1", "configuration_name": "proxy", "service_name": "proxy", "revision_name": "proxy-hvnfg", "project_id": "restored-temecula-mobile-app" } }, "timestamp": "2022-11-14T20:13:43.663181Z", "severity": "ERROR", "labels": { "instanceId": "0074e2ccb212737e5aad036cd3cebcfe4d5f35f47d168e939180e59572278e50b0cb6b75be2da34e4a6c16bbab33905987e3d9640d703e97d54f9708a58c14dc9f29", "goog-managed-by": "cloudfunctions" }, "logName": "projects/restored-temecula-mobile-app/logs/run.googleapis.com%2Frequests", "trace": "projects/restored-temecula-mobile-app/traces/9dacc5993e58e51bcd37c3c3b8b461e6", "receiveTimestamp": "2022-11-14T20:13:43.670755140Z", "spanId": "17443868335897408337" }

Lastly, when I attempt to perform the POST request in terminal using CURL, I receive the same response as if I were simply navigate to the link (https://proxy-hwp6dcya3a-uc.a.run.app/https://exp.host/--/api/v2/push/send) in my browser. E.g below shows the CURL command follow by the response, directly copied from terminal and pasted here.

curl -H "Content-Type: application/json" -X POST "https://proxy-hwp6dcya3a-uc.a.run.app/https://exp.host/--/api/v2/push/send" -d '{ "to": "ExponentPushToken[dhLJeWNqW61r1ZBUkAwOtA]", "title":"hello", "body": "world" }' Missing required request header. Must specify one of: origin,x-requested-with%

"Missing required request header. Must specify one of: origin,x-requested-with"... Would love any assistance on this! Thanks in advance!

Firstly, thank you for this repo, it is such a lifesaver for CORS related problems. But there is an issue that I faced when using the Firebase version. When I use the https://cors-anywhere.herokuapp.com/ as a proxy, I can scrape the YouTube urls without any problem, but when I try to use my server It gives me video is not available response. Do you have any idea what causes this issue? Other urls works fine btw.

How do I make it work on fastly.com?
