Issue in executing transaction using testrpc in truffle

Question

I have created an app using truffle and testrpc. I have verified the contract functions using truffle console..It worked. But while executing the transaction from front-end it is getting the following error in the console of testrpc. How can I resolve this error?Is it possible by updating the gasPrice field in truffle.js?

  Transaction: 0x59b171fbc29cf9f89506f3f1a37bd6010863ae773c264e4f349477f1f3a47b71

  Runtime Error: invalid opcode

Any help is appreciated

Answer 1

'Invalid opcode' means your contract has throw an exception, for example a require or assert has failed, division by zero, reading from unassigned memory, calling to an invalid address, etc.

You have to check the function that is failing for conditions that can cause an error.
