[Bug] File Datasource Indexing Failing Due To Database Constraint Violated Error

[itsjerryokolo]

Bug report

I deployed this subgraph to Studio
https://github.com/ebarvatech/subgraph-ipfs-poc but it's failing with the error below. This is the same error @ebarvatech initially reported.

Deployment: QmPx8bnb49ehT4DX1DPF6iTvtR2ihSP1FwRcABNBdnaYcB

Subgraph writer failed, error: database constraint violated: duplicate key value violates unique constraint "metadata_pkey": Key (vid)=(153163558887096420) already exists., runner_index: 1049

I assumed this was due to Metadata entity trying to overwrite itself upon multiple triggers, I attempted to trigger this handler just once in a new deployment(QmY6EjGQULAp9Ha3p4JgPABPfV827VxH2yMSYh6mtwbPZL), but it has now failed also with the error below

Error: Failed to transact block operations

@ebarvatech did mention in the chat that he runs the purchase method once (on a new contract). As a result - the same error (database constraint violated:). Any creation 2+ same IPFS data sources in one transaction causes the indexing error

Relevant log output

Deployment:  
Error: Failed to transact block operations
