Hey, this has already been addressed in #7574.

There @BazookaMusic attributes this to a regression in the way HttpContent is cleared, introduced in version 23, with a fix already pending release.

Thank you, just saw the 7574, glad it has been addressed. Just wondering, until it release, we cannot use API integrations bug fixing should get high priority

Anyway thank you for this

If you can't wait, in the meantime you might be able to bypass the error by either:

1. Avoiding the HttpContent.Clear() call before you call HttpContent.GetHeaders
2. If the call is absolutely necessary in your logic you could call HttpContent.WriteFrom('') inbetween the Clear and the GetHeaders.

That is,

HttpContent.Clear();
HttpContent.GetHeaders(HttpHeaders);

gives you the error in the GetHeaders call but

HttpContent.Clear();
HttpContent.WriteFrom('');
HttpContent.GetHeaders(HttpHeaders);

would not.

The issue is fixed in the latest release, but we were unable to release the fix due to a deployment freeze because of the time period. The workaround suggested should also fine and the fix will now be released.

Thus, I will close the issue.
