# Class: InvalidMessageValueError

Defined in: [packages/bitbadgesjs-sdk/src/transactions/messages/bitbadges/tokenization/fromJson.ts:72](https://github.com/BitBadges/bitbadgesjs/blob/master/packages/bitbadgesjs-sdk/src/transactions/messages/bitbadges/tokenization/fromJson.ts#L72)

Error thrown when `encodeTokenizationMsgFromJson` recognized the typeUrl
but the wrapper-class constructor threw on the malformed `value` (missing
required fields, wrong types, etc.). Wraps the underlying TypeError so
agents and HTTP callers see "/tokenization.MsgX: missing field foo"
instead of a raw `Cannot read properties of undefined (reading 'foo')`
stack trace.
