py2neo.errors.ClientError: [Procedure.ProcedureNotFound]

I am trying to connect and import a prov file which was created using GitLab2Prov. When running the code given in the documentation, I run into the below error.

Traceback (most recent call last):

py2neo.errors.ClientError: [Procedure.ProcedureNotFound] There is no procedure with the name db.indexes registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.

I am trying to connect to a local neo4j DB which is newly created and thus doesn't contain anything. The format for importing data is json.

I was hoping to just run it on a new instance but it appears that first the DB needs to be setup with some files. What exactly needs to be done as I couldn't find it mentioned in the document for prov2neo.

Any guidance is appreciated. Thanks

I answer your duplicated question here: https://stackoverflow.com/questions/76062685/py2neo-errors-clienterror-procedure-procedurenotfound-there-is-no-procedure-w/76062879#76062879.

I think the best way forward for this library is to move away from Py2neo and use the official Python driver.
It seems to only use Py2neo for the Bolt connectivity part, so the replacement should not be too painful.

@fbiville thanks for the response. Your suggestion to downgrade and try worked.
