IOS - WKWebView upload file

I have a problem with my iPhone app that only happens on iOS version 13.5. I have a webview (WKWebView) that contains a photo upload form using JQuery, but when selecting the image in the Photo Library the error below occurs and for this reason, the build in the Apple Store is disapproved.

[assertion] Error acquiring assertion: <NSError: 0x600000e2fcf0; domain: RBSAssertionErrorDomain; code: 2; reason: "Client is missing required entitlement"> {
    userInfo = {
        RBSAssertionAttribute = <RBSLegacyAttribute: 0x7ff8776120e0; requestedReason: FinishTaskUnbounded; reason: FinishTaskUnbounded; flags: PreventTaskSuspend>;
    }
}
