Non-static method 'sign' should not be called statically

[philwamba]

Hello,

I've encountered an issue while trying to generate a signed URL. I'm getting an error that says: "Non-static method 'sign' should not be called statically."

Here's the code snippet where I'm experiencing the error:

use Spatie\UrlSigner\Laravel\UrlSigner;

$temporaryUrl = $urlSigner->sign($url, now()->addMinutes(30));

Could you please provide some guidance on how to resolve this error? Any help would be greatly appreciated. Thanks.
