6187 - Radiant 3.1 and below: Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('file://') does not match the recipient window's origin ('qrc:')."
Description:
This error is reported from the web engine in Radiant. The gui platform Qt 5.15 in Radiant integrated a new Web engine to show the html style report. We also can't reproduce this issue on our test environment and couldn't find any reason after reviewing the code. This web engine is build based on Google's Chromium which uses a multi-processes architecture. Now we had observed some weird error messages from Web engine side while executing the communication between main gui and the report page.
To avoid this kind of concern, Radiant will not output such messages by default. The possible reason for the message to be seen is that a debug switch is turned on in the machine.We believe these are not harmful and mostly are according to the communication delay between the main gui and the back-end web rendering process under some specific environment.
Solution:
This output message is already removed and fixed in Radiant 3.2 and higher versions.
