Restore from Backup fails

[guyaevans]

I am trying to restore a backup but it fails with:

remark42  | 2024/06/05 21:49:45.910 [INFO]  {logger/logger.go:134 logger.(*Middleware).Handler-fm.(*Middleware).Handler.func1.1} POST - /api/v1/admin/import?site=remark&provider=native - localhost - efaf335c4b7d - 202 (37) - 708.568µs - {"version":1,"users":[],"posts":[]} {"id": "1", "pid": "", "text": "<p>Hello, Just testing the comment system ;)</p>", "user": {"name": "Guy", "picture": "", "ip": "", "admin": false, "id": ["anonymous_46f13299136675607afcc89cd11d611070cfb4f4"]}, "locator": {"site": "remark", "url": "/posts/2022-11-13_bgp-ipv4-config-on-mikrotik-routerosv7/"}, "score": 0, "vote": 0, "time": "2022-12-22T17:29:49Z", "title": "BGP IPv4 Config on Mikrotik RouterOSv7"} {"id": "2", "pid": "", "text": "<p>I've enjoyed The Missing Crypto Queen for years now.

remark42  | 2024/06/05 21:49:45.917 [WARN]  {api/migrator.go:242 api.(*Migrator).runImport} import failed, failed to save 18 comments

This is the command I am using inside the docker container to trigger the restore:

remark42 restore -s remark -p var/backup/ -f output.gz --url http://localhost:8080

and its output:

remark42 v1.13.0-661f042-20240512T15:03:47
2024/06/05 21:49:45.905 [INFO]  {cmd/restore.go:21 cmd.(*RestoreCommand).Execute} restore output.gz, site remark

2024/06/05 21:49:45.912 [INFO]  {cmd/import.go:63 cmd.(*ImportCommand).Execute} completed, status=202, {"status":"import request accepted"}

This is an extract of the backup file:

{"version":1,"users":[],"posts":[]}

Let me know if you need anything else

Sorry, I am new to this project. But what I found is that the backup file has invalid structure for the user.id. Inside the backup file you have an array, but the system requires a string.

Indeed that was the issue thanks !

Also should be noted the post url must be the full url for the page

@guyaevans, was the backup generated by the migration from another platform, from remark42 itself or manually?

Could some documentation be clarified to prevent this from happening to others?

I definitely should improve import error messaging so that the problem would be visible to the caller.
