GraphQL ProductFilterInput Requires Field to be a String #14312
Description
Every field of the ProductFilterInput input field in Magento_CatagolGraphQl::etc/graphql.xml has the type FilterTypeInput. The problem here is that FilterTypeInput requires most of its arguments to be strings.
For example, I might want to select products that do not have a special price set. This might be some query like:
{
products(filter: { special_price: { null: true } }) {
total_count
}
}The devdocs, and basic intuition seem to suggest this is okay. However, this doesn't work because Magento_GraphQl::etc/graphql.xml requires the null field in FilterTypeInput to be a string.
Preconditions
- This is GraphQL, so it's in
2.3-develop, natch.
Steps to reproduce
- Try to submit the query written above.
Expected result
Based on the documentation, I would expect this to be a legal query.
Receive a response like this:
{
"data": {
"products": {
"total_count": 0
}
}
}Actual result
Response:
{
"errors": [
{
"message": "Argument \"filter\" has invalid value {special_price: {null: true}}.\nIn field \"special_price\": In field \"null\": Expected type \"String\", found true.",
"category": "graphql",
"locations": [
{
"line": 2,
"column": 20
}
]
}
]
}This also applies to other fields. For example, I was unable to filter products by category ids.
