👋 @ctemkar

NOTE: This comment is auto-generated.

Are you sure you have already searched for the same problem?

Some people open new issues but they didn't search for something similar or for the same issue. Please, search for it using the GitHub issue search box or on the official inappwebview.dev website, or, also, using Google, StackOverflow, etc. before posting a new one. You may already find an answer to your problem!

If this is really a new issue, then thank you for raising it. I will investigate it and get back to you as soon as possible. Please, make sure you have given me as much context as possible! Also, if you didn't already, post a code example that can replicate this issue.

In the meantime, you can already search for some possible solutions online! Because this plugin uses native WebView, you can search online for the same issue adding android WebView [MY ERROR HERE] or ios WKWebView [MY ERROR HERE] keywords.

Following these steps can save you, me, and other people a lot of time, thanks!

I'm getting the same error after upgrading to latest version of Flutter. (3.7.10)

[jaroslawdabrowski]

So I had the same issue. I spent some time to find the reason. It seems that this is due to the dependency bot that have updated the androidx.webkit version from 1.5.0 to 1.6.0 and later also to 1.6.1. The new version of android webkit does not know anything about the REQUESTED_WITH_HEADER_CONTROL and therefore we see this exception.
Short term solution is to downgrade webview_flutter_android, 3.3.0 seems to work fine.

@pichillilorenzo can you or someone from your team take care of it? It seems that REQUESTED_WITH_HEADER_CONTROL is not longer supported, so it has to be removed and cleaned up. Thanks.

[ctemkar]

Thanks a lot, will try it
