CORS status error REST API Sap Build Apps

[berry1103]

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

I just tried with sample example in restdb.io ... I am able to get results without CORS

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!

After seeing your screenshot, there is mistake of KEY and which should be x-apikey

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.

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?

yoganandamuthaiah solution is perfect

If you want an SAP BTP or SAP Build Apps solution, you can of course use a destination and then you can use your original key.

Good luck on your project
