Hello Alexandre, It is difficult to offer support directly in this Group, as confidential, project-related information is needed to start investigating, and then progress is not always visible. You are at an advantage posting in the Public Issue Tracker <https://issuetracker.google.com/>, where, by the way, a similar issue <https://issuetracker.google.com/74469012> is already present. This might be caused by a temporary resource scarcity in the Cloud, or by errors in your app's code. It is difficult to say, without a more in-depth investigation.
