Importing (JSON2) fails with "Cannot read properties of null (reading 'localizations')"

[akarelinsbs]

I have a localised instance v4.4.5 with the latest version of Import/Export plugin.

The instance has two languages enabled (Italian & English).

When I try to import the following JSON2 entity

{ "version": 2, "data": { "api::allergen.allergen": { "1": { "id": 1, "name": "Glutine", "description": "Cereali, grano, segale, orzo, avena, farro, kamut, inclusi ibridati e derivati." } } } }

it fails with

"Cannot read properties of null (reading 'localizations')"

error.

I have encountered the same error when localization: [] in the json.

Once I added localization for 1 entry, the import went but, that's not feasible for all entries.

In the following example I am getting an error even with localizations present for 2 entries.

	"version": 2,
	"data": {
		"api::page.page": {

Hey @mmange @akarelinsbs this is the issue I am currently working on. I made significant progress and I will have a fix by end of next week

Feel free to join the discord of the community (see readme) to have the latest updates

[Baboo7]

I published version 1.17.0 that focuses on exporting/importing single types with json v2 format

[JWesorick]

I am using 1.18.0 and have a very similar error when importing with v2:

Cannot read properties of undefined (reading 'attributes')

This is just doing a "Quick Actions" export and then trying to import it.

[Baboo7]

Can you share the schema of the collection that triggers the issue?

[JWesorick]

Here is my import json

{
  "version": 2,
  "data": {
    "api::playlist.playlist": {
      "139": {
        "id": 139,

        "slug": "abc-123",

@JWesorick the issue I see is that all collections are part of the data of the collection api::playlist.playlist

[JWesorick]

🤦🏻 Yea that was it. Correctly formatting the JSON makes it work.

[m-torin]

@JWesorick what did you change to make the JSON formatted correctly? Your snippet passes validation.

[Baboo7]

@m-torin you can find an example in the doc in the Importing Data section.

Here the issue was the collections were nested in another collection instead of being in the object data
