ERR_BLOCKED_BY_RESPONSE error on webos 22 TV

We are developing an app using a webos 22-based simulator and real equipment. When calling our internal backend API, no error occurs in the simulator, but an error occurs on the actual TV equipment. The error details are as follows.

Also, the error does not occur when testing on a webos 23 physical TV with the same ipk file.
Below are the header details for the request.

If the request is successfully performed, sec-fetch-mode in the request header is set to cors.

Please share with us the following at

  • Your app .ipk file
