Rest API is allowing duplication for attribute options and also always returning an empty option

[abdulmoizbaig]

Preconditions:

1. Magento 2.1.5 or 2.1.7

Steps to reproduce:

1. Use this endpoint to add options for an attribute V1/products/attributes (catalogProductAttributeRepositoryV1) and trying adding similar values for each option's label.
2. Use this endpoint to get options of attribute that you added in the step 1 V1/products/attributes/{id}/options (catalogProductAttributeOptionManagementV1)

Actual Result:

{"is_wysiwyg_enabled":"","is_html_allowed_on_front":"","used_for_sort_by":"","is_filterable":"","is_filterable_in_search":"","is_used_in_grid":"","is_visible_in_grid":"","is_filterable_in_grid":"","position":"0","apply_to":[],"is_searchable":"0","is_visible_in_advanced_search":"0","is_comparable":"0","is_used_for_promo_rules":"0","is_visible_on_front":"0","used_in_product_listing":"0","is_visible":"1","scope":"global","attribute_id":"136","attribute_code":"aaattribute","frontend_input":"select","entity_type_id":"4","is_required":"","options":[{"label":"","value":""},{"label":"ThisIsATestValue","value":"4"},{"label":"ThisIsATestValue","value":"5"},{"label":"ThisIsATestValue","value":"6"}],"is_user_defined":"1","default_frontend_label":"aaattribute","frontend_labels":"","backend_type":"int","source_model":"Magento\\Eav\\Model\\Entity\\Attribute\\Source\\Table","default_value":"6","is_unique":"0","validation_rules":[]}

Expected result

{"is_wysiwyg_enabled":"","is_html_allowed_on_front":"","used_for_sort_by":"","is_filterable":"","is_filterable_in_search":"","is_used_in_grid":"","is_visible_in_grid":"","is_filterable_in_grid":"","position":"0","apply_to":[],"is_searchable":"0","is_visible_in_advanced_search":"0","is_comparable":"0","is_used_for_promo_rules":"0","is_visible_on_front":"0","used_in_product_listing":"0","is_visible":"1","scope":"global","attribute_id":"136","attribute_code":"aaattribute","frontend_input":"select","entity_type_id":"4","is_required":"","options":[{"label":"ThisIsATestValue","value":"4"}],"is_user_defined":"1","default_frontend_label":"aaattribute","frontend_labels":"","backend_type":"int","source_model":"Magento\\Eav\\Model\\Entity\\Attribute\\Source\\Table","default_value":"6","is_unique":"0","validation_rules":[]}

Additional information

1. It always returns an empty option as you can see ({"label":"","value":""}) in actual result.
2. It should not add duplicates as you can see in actual result({"label":"ThisIsATestValue","value":"4"},{"label":"ThisIsATestValue","value":"5"},{"label":"ThisIsATestValue","value":"6"}) because its not allowed from admin panel too. It should say something like "already exist".

Hi @abdulmoizbaig

@abdulmoizbaig, thank you for your report.

Unfortunately, we are archiving this ticket now as it did not get much attention from both Magento Community and Core developers for an extended period. This is done in an effort to create a quality, community-driven backlog which will allow us to allocate the required attention more easily.

Please feel free to comment or reopen the ticket if you think it should be reviewed once more. Thank you for collaboration.
