> The error occurs because Polkadot-JS now expects account backup files in array format [{…}] rather than the older single-object format {…}. The fix is straightforward: wrap your JSON content in square brackets. old way: {"address":"5GrwvaEF...","encoded":"0x...","encoding":{...},"meta":{...}} new way: [{"address":"5GrwvaEF...","encoded":"0x...","encoding":{...},"meta":{...}}] i.e. Add [at the very beginning of the file Add] at the very end of the file Save the file
