got a 400 error when running set_app_key in jupyterlab instead of codebook

I got a 400 error when running set_app_key in jupyterlab instead of codebook.

The key works well in codebook.

Please be informed that the resolution posted in the support ticket is as the below

Even though the HTTP request is directed to the localhost, your HTTP proxy intercepts it. After intercepting the request, the proxy returns the request to your machine, but now to Eikon API Proxy, the request appears as coming from a remote machine (as it comes from the IP address of the HTTP proxy). Eikon API Proxy rejects the request with the error message that you've seen because it only allows requests coming from the same machine.

The client need to configure proxy settings to allow HTTP requests directed to the localhost to not be intercepted by your HTTP proxy

Hi @rayr.hou ,

To access Eikon Data API via Jupyter Notebook, you need to connect to the API using the APP key. APP key can be generated via APPKEY Generator app (type APPKEY in Search box) within Eikon/Workspace.

After you have an API key you can connect to the API using the query below

import eikon as ek
ek.set_app_key("YOUR APP KEY")

In the example above I have put the APP key directly in the code, however for security purposes you may want to read the APP key from a local txt file, config file or an environment file.

Hope this helps, please let me know if you have any further questions.

Best regards,

Haykaz

Hi Haykaz,

I ran the same code you provided with my APP key.

The errors are shown as below

I can confirm the app key is correct as it runs perfectly in codebook

Hi @rayr.hou ,

Do you have eikon/workspace running on the background? It should be open to connect to Eikon API via the desktop session.

Best regards,

Haykaz

rayr.hou

yes, I have eikon running on the background. I am working on the VPN machine for your information

And do you have API Key active in APPKEY generator app like this?

rayr.hou

yes, I do.

I have created a support ticket on behalf of you to verify your APP key. The Eikon team will connect you for the details.

I still do not figure it out. I found my URL is http://localhost:9001/api/. If someone knows how to fix it?

and the error shows

ERROR:pyeikon:Error on handshake url http://localhost:9000/api/handshake : EikonError(1, 'Status code 400: App key is incorrect')
