Getting error `signature` is required during upload in angular

I am getting error as soon as I replace my apikey with the demo apikey.

Below is the network response
“error”: {
“status_code”: 400,
“content”: “signature is required.”,
“error_code”: “SignatureRequiredError”

Not sure what’s wrong here. Could not find anything in the documentation either. Please help.

Hello Neeraj. Arch here from Uploadcare.

Could you please send me the bigger chunk of your code? It’s hard to see the issue with only the error message.

Best regards.

Could you share the exact API key you’re using? If it’s demopublickey, this error should not occur.
