cannot get the contract agreement id

[ghost]

Hi,
I wanted to add the eu-policy from the policy sample into the transfer sample but I am stuck at the contract negotiation. I set the eu-policy equal to the contract policy. If I try to curl the negotiation status, I get this:

 curl -X GET "http://localhost:29193/management/v2/contractnegotiations/29959b5b-d086-4895-9cb1-7e1097e0e5eb" \
  --header 'Content-Type: application/json' \
  -s | jq

{
"@type": "ContractNegotiation",
"@id": "29959b5b-d086-4895-9cb1-7e1097e0e5eb",
"type": "CONSUMER",
"protocol": "dataspace-protocol-http",
"state": "REQUESTED",
"counterPartyId": "provider",
"counterPartyAddress": "http://localhost:19194/protocol",
"callbackAddresses": [],
"createdAt": 1714678339218,
"@context": {
"@vocab": "https://w3id.org/edc/v0.0.1/ns/",
"edc": "https://w3id.org/edc/v0.0.1/ns/",
"odrl": "http://www.w3.org/ns/odrl/2/"
}
}
The state is on "requested" and how do I get "finalized"?
How do I get the contract agreement id to perform a data exchange?
Thanks in advance

hi, you should take a look at the logs, because the state should move from REQUESTED quickly, if not, there's something wrong (nit: please wrap code/commands in triple tick blocks ``` so they become readable)

Hi, thanks for your response. I am very new to this and I don't know everything yet. Where can I take a look in the logs and what should I be looking for?

[ndr-brt]

if you followed the sample README you should have run some commands in your command line, particularly, you should have started 2 connectors, they print logs in the console

@Tulpe1 You need to watch the status keyword.

The provider should print something like:

Both should reach FINALIZED. If this is the case, the GET on negotiations/uuid will result in an object containing a contractAgreementId property. If not, some error causes should be printed in the logs.

Thanks, I have found my mistake.
