Error Codes
Vault exceptions will revert with "BAL#" instead of text; see below for the interpretation of the number.
Code | Error | Comment |

001 | SUB_OVERFLOW | |
002 | SUB_UNDERFLOW | |
003 | MUL_OVERFLOW | |

Code | Error | Comment |
100 | OUT_OF_BOUNDS | |
101 | UNSORTED_ARRAY | See UNSORTED_TOKENS |

203 | MIN_SWAP_FEE_PERCENTAGE | |
204 | MINIMUM_BPT | On pool initialization, a small amount of BPT is minted to the zero address (keeps math well behaved). If initial balances are too small, initialization can fail |
205 | CALLER_NOT_VAULT | Certain pool callbacks need to be external, but could be exploited if called by anyone but the Vault |

329 | PRICE_RATE_OVERFLOW | Rate returned from a rateProvider must fit in 128 bits |
330 | INVALID_JOIN_EXIT_KIND_WHILE_SWAPS_DISABLED | Investment pools only allow proportional joins and exits when swaps are disabled (to prevent unbalancing the pool) |
331 | WEIGHT_CHANGE_TOO_FAST | Gradual weight update duration too short (minimum 1 day) |
332 | LOWER_GREATER_THAN_UPPER_TARGET | Invalid Linear Pool operating range |
333 | UPPER_TARGET_TOO_HIGH | Linear Pool max balance must fit in 112 bits |
334 | UNHANDLED_BY_LINEAR_POOL | Some joins/exits are pool type-specific |
