Issues exists in magento 2.2.2

[SolsWebdesign]

Issue also in 2.2.3 I would very much like to (re)open this issue.

Preconditions:

1. Magento 2.2.3 (store A) without sample data installed (note that this problem also occurs in Magento 2.2.2)
2. Another Magento 2.2.3 (store B) is installed with migrated products from a Magento 1 store (in my case a Magento 1.8.1.0 store)
3. Create a product in the new store A (Magento 2.2.3), export and import it. Goes fine.
4. Export one or more product(s) from store B (Magento 2.2.3) with migrated products (note: no changes are made to the export file).
5. Import the newly created CSV file in store A (the first Magento 2.2.3 with no migrated products, just that one test product). Choose Entity Type Products (other settings don't really matter but try to keep them consistent with the settings used when exporting from store B). Choose the file you exported from store B with the migrated products and hit the button "Check Data".

Expected result:
Maybe some errors indicating things need to be changed in the CSV file or maybe some message saying it isn't compatible.

Actual result:
An endless rotating "Please wait" icon....

But when opening the console you can see the Internal Sever error:

Some digging around in the logging gives me the following:

[28-Mar-2018 18:53:35 UTC] PHP Fatal error: Uncaught Error: Call to a member function getFrontendInput() on boolean in ....
/vendor/magento/module-catalog-import-export/Model/Import/Product.php:2657
Stack trace:

4 ../vendor/magento/module- in /home/scrittu/public_html/vendor/magento/module-catalog-import-export/Model/Import/Product.php on line 2657

Deleting the attribute that seems to be the problem (in my case adwords_grouping even though I had created this in store A as well) just gets me onto the next Internal Server Error:
[28-Mar-2018 19:15:47 UTC] PHP Fatal error: Uncaught Error: Call to a member function getFrontendInput() on boolean in /home/scrittu/public_html/vendor/magento/module-catalog-import-export/Model/Import/Product.php:2657
Stack trace:

0 ../vendor/magento/module-catalog-import-export/Model/Import/Product.php(2593): MagentoCatalogImportExportModelImportProduct->parseAttributesWithWrappedValues('brand_se="Bomo ...')

and another attribute that exists in both stores becomes the problem.

I still need to investigate this further (so far I have created various products and exported and imported these fine in Magento 2.2.x stores and have exported migrated products fine but haven't been able to import these again) but I think Magento 2.2.2/2.2.3 should not throw an Internal Sever error when someone pushes the Check Data button.

I will add further findings.

Same issue on fresh installed 2.3.0 on check data

[AndyJAllen]

I receive this issue on 2.3.3 when clicking check data. Can't import products. There's no issues importing customer data though.

Nothing pertinent in exception or system log files. Network monitor shows 500 Internal Server Error on /admin/import/validate/key/_removed_/?form_key=_removed_

Edit: I ended up figuring out that this was caused by the module Magento_Downloadable being disabled. It seems this module became necessary to have enabled in one of the 2.3 updates; as far as importing products goes.

Magento 2.3. trying to do a product csv import.

This is an issue when Fields enclosure box is ticked, which needs to be ticked to get special characters otherwise it stuffs up the encoding and gets scrambled stuff which might push some attributes such as meta_description past their 255 length validation.

Magento_Downloadable is irrelevant, but is enabled.
