requestFocus() call crashes on iOS

Bug description: When I call requestFocus() on a webview I'm getting this error: dispatchViewManagerCommand must be called with a string or integer command This happens only on iOS, android looks OK.

To Reproduce: Pull the repro I made here: https://github.com/alexisbronchart/WebViewFocus

Expected behavior: The app should load the webview with the text input already focused as it does on android.

Environment: - OS: iOS - OS version: 13 - react-native version: 0.61.4 - react-native-webview version: 7.5.1

    If anyone is running into this issue, you should be able to set the keyboardDisplayRequiresUserAction prop to false (for IOS) and then request focus by using the injectedJavaScript prop.

    Pseudo Code Example

    const INJECTED_JAVASCRIPT = `(function() {
        var inputId = 'search_input_react';
        var searchInputElement = window.document.getElementById(inputId);
        if (searchInputElement) {
    <webview source="{{" uri: injectedjavascript="{INJECTED_JAVASCRIPT}" keyboarddisplayrequiresuseraction="{false}"></webview>;

    Issue is still here. thanks for the workaround. In my current use case I also had to call blur before focus to get it to work.

    Issue persists for me with the exact same error message, dispatchViewManagerCommand must be called with a string or integer command

    • react-native-webview.7.0
    • expo.0.3

    I absolutely cannot find a workaround here. Does anyone have any tips?

    In our case, we're trying to focus the a DOM node using this.webview.current.injectJavaScript([ourcommand]) instead of injectedJavaScript prop, but the injected code is essentially the same, and we get the same error as OP.

    , I assume you mean you had to blur a DOM element inside the webview, right? Because as far as I can tell the webview itself doesn't have a blur method. Were you getting an error without blurring, or just a lack of focus?
