EDIT 1:

I have done more testing and I found out That when I use latest version of surreal and surrealist I can't see my data or access on My API layer but now I reverted my surreal back to 1.0 and surrealist to 1.11.0 and I can see my data and my api can access the data

Hi @mimib00, can you confirm that the rocksdb file storage has the same file size still?

[mimib00]

Hi @mimib00, can you confirm that the rocksdb file storage has the same file size still?

Yeah that's the weird thing the data was still on the disk but surrealdb 1.4.2 and surrealist 2.0.5 can't see it for some reason

I have edited the main bug question with more details you can check it

Hey @mimib00, did you upgrade from v1.0.0? Or perhaps one of it's beta's

Hey @mimib00, did you upgrade from v1.0.0? Or perhaps one of it's beta's

The database was in 1.0.0 and updated to v1.4.2 using docker-compose

[phughk]

@mimib00 can you confirm the docker volumes you have please?

[mimib00]

he docker volumes you have please?

what do you mean by that?

if you mean that the volume exists and has permissions it does cause as soon as I reverted the database version in the docker-compose file to 1.0 every worked just fine and the data is there

[phughk]

Could you please export the 1.0 database and import it into the latest (either 1.4 or 1.5).

I was wondering if it was the case that a separate image would have had separate storage, explaining the above.

Either way, exporting and importing should solve the problem, whatever the underlying infra issue is. The data will only disappear if it isn't found.

I'm busy with other projects at the moment, but I'll give it a try as soon as I'm free and update you here

@mimib00 there's a bug I also encountered on Surrealist when upgrading surrealDB versions. In my case the data is not lost, Surrealist just can't show the results in the UI, if you manually query your data you should be able to see it.
