Hello! I’m using Tyk Gateway OSS edition.
I have the following GraphQL schema (I simply used a schema from the
public Country API):
type Country {
code: ID!
name: String!
}
input StringQueryOperatorInput {
eq: String
ne: String
in: [String]
nin: [String]
regex: String
glob: String
}
input CountryFilterInput {
code: StringQueryOperatorInput
currency: StringQueryOperatorInput
continent: StringQueryOperatorInput
}
type Query {
countries(filter: CountryFilterInput): [Country!]!
}
Then I’m trying to run a query with a minor error: an extra field is added to the input parameters:
Query:
query MyQuery($filter: CountryFilterInput) {
countries(filter: $filter) {
code
name
}
}
and values:
{
"filter": {
"code": {
"in": [
"US"
],
"extra": "value"
}
}
}
Please notice extra input field in the variables.
When I run the query above, Tyk fails with a panic error. Here’s a piece of Tyk log:
