The project was setup a while back when the blockchain was accessed via
but that gives the error: project ID not provided
Using /v2 gives the same error
Using /v3 gives basic auth error
for a simple eth_blockNumber call
Is there a process to change/migrate older projects to v3?
Hi Phil, welcome to our community.
There was not a process to migrate the old Project IDs to be valid as a v3 ID. What you will need to do is register for an account at https://infura.io and generate a new Project. The full process is outlined here, though it is pretty straightforward. https://blog.infura.io/getting-started-with-infura-28e41844cc89/
That should get you going again, thanks!
