Hi Đoàn,
The reason you're getting this error is because content-type header is missing in the response from the URL. You can check this by running the following in your terminal: curl -i "https://api.biabudvar.cz/api/media/public/89acebd35105a5f73f29dec513b10bcfbd.jpg". This will show the headers of the response. The Content-Type header should indicate the MIME type(e.g., image/jpeg). If you control the image hosting server, ensure that the correct Content-Type is set in the HTTP headers for the file.
