In fact I have made a little mess, after your comment I've realized it, the wallet with the blackbytes to be transferred I have just discovered was an old FULL node wallet which I've opened with a light wallet app just by renaming the data folders - it's quite logic it wouldn't work I guess. To get it work I suppose I should restore an old backup. Well, this would be good news, it means no bugs in Byteball wallet and some bugs just in my mind

Don't hesitate if you still have issues.
still dont works after restore frome backup i buy some gbb and that whats sow up
Uncaught exception: Error: Error: SQLITE_ERROR: no such index: outputsIsSerial SELECT unit, message_index, sequence FROM outputs INDEXED BY outputsIsSerial JOIN units USING(unit) WHERE outputs.is_serial IS NULL AND units.is_stable=1 AND is_spent=0
Can you please give some details about what you exactly did? (If the issue is with buying GBB, maybe the maintainer of the bot you are using to buy could help.)
