Here's a tighter loop around the issue: https://arweave.net/graphql QUERY: query { transactions( first: 2147483647 owners: ["z_TqsbmVJOKzpuQH4YrYXv_Q0DrkwDwc0UqapRrE0Do"] tags: [ { name: "Type", values: ["update-ref"] } { name: "Repo", values: ["Gitopia"] } ] ) { edges { node { id tags { name value } } } } } RESPONSE: { "data": { "transactions": { "edges": [ { "node": { "id": "GEJSszMKteClrXm6U_VeQbXf3hnTNhGVlukrxDEymNM", "tags": [ { "name": "Repo", "value": "Gitopia" }, { "name": "Version", "value": "0.0.2" }, { "name": "Ref", "value": "refs/heads/master" }, { "name": "Type", "value": "update-ref" }, { "name": "App-Name", "value": "Gitopia" }, { "name": "Unix-Time", "value": "1618562026" }, { "name": "Content-Type", "value": "application/json" } ] } },... So, there's arweave.net's graphql, showing it does indeed have a transaction with ID GEJSszMKteClrXm6U_VeQbXf3hnTNhGVlukrxDEymNM . Maybe I can visit activity of address z_TqsbmVJOKzpuQH4YrYXv_Q0DrkwDwc0UqapRrE0Do near timestamp 1618562026 to see if this is some bundled transaction or something.
