Bug: EDC Data Plane Ignores Proxy HTTP Method

[nicoprow]

Bug Report

Describe the Bug

The EDC data plane accesses an asset only with GET even though proxyMethod has been set to "true" in the asset definition.

Expected Behavior

Given proxyMethod is set to "true" in the asset: the EDC data plane should access an HTTP data resource with the same HTTP method with which the public API endpoint has been invoked.

Observed Behavior

The EDC data plane only uses GET for access.

Detailed Description

Error Path with POST request

1. Created Asset:
   { "@id": "f1cc608f-439b-4fce-aa95-0da0de566f9b", "@type": "Asset", "properties": { "https://purl.org/dc/terms/subject": "cx-taxo:ReadAccessPoolForCatenaXMember", "https://purl.org/dc/terms/description": "Grants the Catena-X Member read access to the Pool API. This can be used to read legal entity, site, address, legal form, identifier type and administrative area level 1 data. To that end, it also grants read access to the respective changelog entries and identifier mappings, as well as relational data.", "https://w3id.org/catenax/ontology/common#version": "6.0", "id": "f1cc608f-439b-4fce-aa95-0da0de566f9b", "https://purl.org/dc/terms/type": "cx-taxo:BPDMPool" }, "dataAddress": { "@type": "DataAddress", "proxyPath": "true", "oauth2:tokenUrl": "https://centralidp.dev.demo.catena-x.net/auth/realms/CX-Central/protocol/openid-connect/token", "oauth2:clientId": "xxx", "type": "HttpData", "proxyMethod": "true", "oauth2:clientSecretKey": "dev/edc/gate/asset-dev-client-secret", "proxyQueryParams": "true", "proxyBody": "true", "baseUrl": "https://business-partners.dev.demo.catena-x.net/pool/v6" }, "@context": { "@vocab": "https://w3id.org/edc/v0.0.1/ns/", "edc": "https://w3id.org/edc/v0.0.1/ns/", "tx": "https://w3id.org/tractusx/v0.0.1/ns/", "odrl": "http://www.w3.org/ns/odrl/2/" } }

2. Perform EDR Negotiation to obtain transfer token

3. Access Data:

curl --location 'https://edc-url.net/api/public/business-partners/changelog/search?page=0&size=10' \ --header 'Content-Type: application/json' \ --header 'Accept: application/json' \ --header 'Authorization: xxx' \ --data '{ "businessPartnerTypes": [ "SITE", "LEGAL_ENTITY" ] }'

4. See error in logs:

Further information

Accessing a GET endpoint on the same asset is working without issues. For example the following request after negotiation gives an expected response:

curl --location 'https://edc-url/api/public/legal-entities?size=10&page=0' \ --header 'Accept: application/json' \ --header 'Authorization: xxx'
