Not able to view the emualtor on the web browser

[hridhar]

Hi,

Please help and support.
I am getting below error while running the emulator in web container.

Jwks remote fetch is failed.

@hridhar thanks for reaching out!

With the current level of details, it's hard to understand what's going on.

It appears that a HTTP 401 is returned — indicating some authentication issues. (it's plausible that some auth headers were not properly passed to the server, and hence the error.)

Can you first try talking to an endpoint that does not require authentication and ensure the basic flow works, and then turn on authentication and debug the auth issue? That might help you isolate the issue.

Hi,

Thanks for the reply,

Please find the below information.
We are able to list the services using below command.
grpcurl -plaintext localhost:8554 list

We are using the below scripts to run the emulator over container.
https://github.com/google/android-emulator-container-scripts

We are fallowing below steps.

1. git clone https://github.com/google/android-emulator-container-scripts.git
2. cd android-emulator-container-script
3. source ./configure.sh
4. emu-docker licenses
5. emu-docker create /path/to/emulator.zip /path/to/system-image.zip
6. /create_web_container.sh
7. docker-compose -f js/docker/docker-compose-build.yaml -f js/docker/development.yaml up

Expected Result:
8.Emulator should run without any issue over web browser.
Point your browser to localhost.

Actual Result:
8. Not able to view the emulator on the web browser.

Error Facing:
We are able to print the token also.

Hi @sampajano

We are getting below error while opening the web browser.

[sampajano]

@hridhar Hihi. Thanks for providing all the details!

I've noticed that in your request header, you have the following auth header:

Authorization : Bearer "TOKEN KEY"

I suppose a proper token was provide above? And yet you're still seeing invalid token error?

Could you try the same request with curl? If you're getting a server 401, and if you are seeing the same error when using curl command, then it's outside of the scope of the grpc-web client library, but rather there's something you need to fix with your server / auth setup.

Hi @sampajano,
Thanks for the help and support.

We have checked the Token and it is valid token.
Header: Verified the algorithm (alg) used for signing.
Payload: Confirmed the content, including expiration (exp), issuer (iss), and any other claims.
Signature: Sign the token.

@hridhar Hi :)

Thanks for providing the above info, although it seems that the auth headers are missing from the logs.

I was earlier suggesting that you use "curl" with all the same request headers which you had passed in the grpc-web request.

You could do that by using the "copy as curl" function in Chrome's network tab.

The primary point being, if this request is failing due to auth issue, it can be caused by any number of reasons, and you should try identifying what exactly is causing it, because you can know if this is a server, client issue, or a combination of both.

Hi @sampajano,

Thank you for explaining and I got your point.
Thank you for your precious time.

Please find below info, and I am surprised that there is no output/error we observed while running the below command.

We are running below commands inside emulator_envoy:latest container.
Command : curl 'http://localhost:8080/android.emulation.control.EmulatorController/getStatus'
-H 'Accept: application/grpc-web-text'
-H 'Accept-Language: en-US,en;q=0.9'
-H 'Authorization: Bearer TOKEN_KEY'
-H 'Connection: keep-alive'
-H 'Content-Type: application/grpc-web-text'
-H 'Origin: http://localhost:8080'
-H 'Referer: http://localhost:8080/'

Hi @sampajano,

Just now I have tried, running the working curl command inside the emulator_envoy:latest container.
We don't see anything error or output or empty space/line. Just it will go to the next prompt (output is same as above).

[sampajano]

@hridhar Hihi. i think you have some formatting issue wrt your curl command. (e.g. what's the >>> in the end?)

Try the following format maybe:

curl 'http://localhost:8080/android.emulation.control.EmulatorController/getStatus' \
-H 'Accept: application/grpc-web-text' \
-H 'Accept-Language: en-US,en;q=0.9' \
-H 'Authorization: Bearer TOKEN_KEY' \
-H 'Connection: keep-alive' \
-H 'Content-Type: application/grpc-web-text' \
-H 'Origin: http://localhost:8080' \
-H 'Referer: http://localhost:8080/' \
-H 'Sec-Fetch-Dest: empty' \
-H 'Sec-Fetch-Mode: cors' \
-H 'Sec-Fetch-Site: same-origin' \
-H 'User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36' \
-H 'X-Grpc-Web: 1' \
-H 'X-User-Agent: grpc-web-javascript/0.1' \
-H 'sec-ch-ua: "Not/A)Brand";v="8", "Chromium";v="126", "Google Chrome";v="126"' \
-H 'sec-ch-ua-mobile: ?0' \
-H 'sec-ch-ua-platform: "Linux"' \
--data-raw 'AAAAAAA='

Also at this point i don't believe this qualifies as a grpc-web "issue", but rather a discussion thread — with regards to fixing auth in your server integration. I'll convert it as one :)
