When I use:
let screenshot_uu = await driver.takeScreenshot();
the returned string is exactly 100_000 characters - suspicious but not invalid - and characters 50_000 - 50_002 are
e2 80 a6 which are not in the valid set for base64 as far as I know.
atob throws a exception on the string
thDOMException [InvalidCharacterError]: Invalid character at atob (node:buffer:1242:7)
On inspection that is what I found those characters above in the string
Have I done something wrong in the way I call
takeScreenshot? Would more context help?
