Only seeing 'COMMITTING' from getPendingTransactions and never 'COMMIT_FAILED'?

Question

I am trying to set up retries, on failed mutations, as documented by Relay: https://facebook.github.io/relay/docs/api-reference-relay-container.html#getpendingtransactions.

I am causing the mutation to fail, on the graphql server, by returning an error:

 mutateAndGetPayload: ({text}) => {
    return new Promise((resolve, reject) => {
      setTimeout(() => {
        resolve(new Error("failed"));
      }, 2 * 1000);
    });
  },

When I first execute the mutation I can see the status of 'COMMITTING'. But then in the next render getPendingTransactions returns null and I cannot figure out how to see a status of 'COMMIT_FAILED'.

var transactions = this.props.relay.getPendingTransactions(this.props.story);

console.log("TRANSACTIONS", transactions);

var transaction = transactions ? transactions[0] : null;

if (transaction) {
  console.log("STATUS", transaction.getStatus());
}

I must be missing something, but so far can't figure it out.

Answer 1

Your transaction with a COMMIT_FAILED will not be in pendingTransactions since it has been tried and failed already. Are you mutating using RelayStore.update ?

You could try creating a transaction using RelayStore.apply_update. This function actually returns the transaction object. You can then call transaction.commit(). If it fails, your transaction object should have a status of COMMIT_FAILED.
