CORS status error REST API Sap Build Apps

Dear Builders,

I am following some tutorials on SAP Build Apps (AppGyver). In one of these tutorials I need to connect a restdb.io server with a rest api direct integration.

When I enter the resource url, the API key and click Get Collection on test, the following error message appears: 'Error: TypeError: Failed to fetch. Does the server allow CORS?status: undefined'.

To overcome the problem I have tried everything, including multiple headers. Nothing works. A colleague tried the same in Postmen. Things went well here.

I have followed the tutorial one on one, but it does not dwell on a possible error message. I get stuck.

Does anyone know a solution that I can use? Thank you in advance!

in you restdb.io while generating key .. you can enable CORS

https://restdb.io/docs/apikeys-and-cors#restdb

Dear Yogananda,server-2.pngserver-3.png

Thank you for the quick response! I (and my colleagues) started working on the documentation.

The test still gives an error. We don't understand what we're doing wrong. I have attached screenshots of our new configuration.

What are we doing wrong?

Could you please look?

Thank you in advance!

Sorry for the late response. I was on vacation from there. In the end, the test was successful. The mistake I made was the following. To avoid the CORS error, I had to create a second website key. This website key replaces the original x-api key. Previously I had both an x-api key and an extra website key. This didn't work.

Many thanks again for the help.

Regards,

Berry

Hi, how can I solve this problem (CORS -Does the server allow CORS?status: undefined) when I want to use the AI Core API or any other API which is available in the SAP SAP Business Accelerator Hub?
