Good morning, I have a problem that I do not even know where to start with several applications in Google App Engine using Java.
It turns out that suddenly the application returns to a previous version of the one I had installed, losing texts from the DataStore and files from the cloud storage.
When the Datasore is erased, I have a listener that if it is empty, the DataStore re-populates it with initial data, but this is not the case since the last uploaded version has other texts. So I think it's not just the datastore and the cloud storage, but it seems to me that the entire Google App Engine application will be restored from an image several months ago. I have the impression that the latest version is uploaded and that all texts and files that were there since then are deleted.
I do not know what happens and when I have seen the problem, I have not arrived in time to see the log (since the old records are deleted after a few days).
I would appreciate any clue that you could give me since I do not even know where to start.
Thank you and greetings.
