Error when trying to import exported block

@megayu is already working on this.

Since Jul 14, 2026.

### Search first

- [x] I searched and no similar issues were found

### What Happened?

I tested importing the EDN export of a block. It failed.

Surprisingly it does work with 2 blocks. The EDN does include the journal page reference.

```
{:pages-and-blocks
[{:page {:build/journal 20260713},
:blocks
[{:block/title "Mittagessen"} {:block/title "Abendessen"}]}],
:logseq.db.sqlite.export/export-type :selected-nodes}
```

In the GUI, i get 2 notifications:

> No block found

> An unexpected error occurred building the import. See the javascript console for details.

But there is nothing in the console!

In the terminal, i get a bit more output.

### Reproduce the Bug

1. Export block as EDN format
2. Import EDN

### Expected Behavior

I expect that the block is added at the end of todays journal, like CLI block upsert.

### Screenshots

### Files

My block. You can use it to test:

```
{:logseq.db.sqlite.export/block {:block/title "Mittagessen"},
:pages-and-blocks [],
:logseq.db.sqlite.export/export-type :block}
```

Terminal output:

```
The build-blocks-tx has the following options errors:
{:pages-and-blocks
[{:page
{:block/title
[":block/title, :block/uuid or :build/journal required"]}}]}

Invalid data for options errors:
{:pages-and-blocks {0 {:page {}}}}
