This is really frustrating. I have a 104 MB JSON file that I want to upload to my Firebase database through the web front end, but after a random period of time (I've timed it, it's not constant, anywhere from 2 to 20 seconds) I get the error:
There was a problem contacting the server. Try uploading your file again.
So I do try again, and it just keeps failing. I've uploaded files nearly this big before, and the limit for stored data in the realtime DB is 1 GB,
I'm not even close to that. Why does it keep failing to upload?
This is the error I get in chrome dev tools:
Failed to load resource: net::ERR_CONNECTION_ABORTED
https://project.firebaseio.com/.upload?auth=eyJhbGciOiJIUzI1NiIsInR5cCI6…Q3NiwiYWRtaW4iOnRydWUsInYiOjB9.CihvjvLSlx43nOBynAJeyibkBRtygeRlG4Yo1t3jKVA
Failed to load resource: net::ERR_CONNECTION_ABORTED
If I click on the link that shows up in the error, it's a page with the words POST request required.
Turns out the answer is to ignore the web importer entirely and use firebase-import. It worked perfectly first time, and only took a minute to upload the whole json. And it also has merging capabilities.
