No Endpoint Generator Function Registered for Source Data Type HttpData

[harshitmahapatra]

Hi everyone,
I was trying to follow the transfer-02-consumer-pull tutorial, after successfully completing the transfer-01-negotiation tutorial.
But when I start the transfer, it seems to stop at "REQUESTED", on the provider I see the error No Endpoint generator function registered for source data type 'HttpData'.

The asset created in transfer-01-negotiation is of type HttpData.
I am using edc version 0.7.0

Here are my logs:

Here are my dependencies

    implementation("org.eclipse.edc:edr-store-receiver:${edcVersion}")
    implementation("org.eclipse.edc:edr-cache-api:${edcVersion}")
}

My guess is I am missing a class or dependency that implements Endpoint generator function registered for source data type 'HttpData'` ?

I am new to dataspaces, so any suggestion would be a great help :) !

hi, this is likely your culprit:
implementation("org.eclipse.edc:data-plane-public-api:${edcVersion}")

you'll need
implementation("org.eclipse.edc:data-plane-public-api-v2:${edcVersion}")

the first one is also deprecated

Thanks a lot! That solved the issue :).
