Issue details

Uncaught exception with nodejs runtime and Pulumi Automation API v3.25.0 (NodeJS 16.13.0)

Uncaught exception: 'Error: ENOENT: no such file or directory, stat '/var/folders/68/g0qw_p0s6lg94ymccg0438h00000gp/T/automation-logs-up-AfbzNQ/eventlog.txt'

Steps to reproduce

1. Use a project with automation API and external program
2. Create a valid program
3. If an error occurs with a resource, the project exit with an uncaught exception

Investigation

After investigating the issue, I saw the problem is in the following line:

pulumi/sdk/nodejs/automation/stack.ts

Line 238 in 05a3eb7

[upResult, logResult] = await Promise.all([upPromise, logPromise]);

upPromise thrown an error, then logResult is not defined. In the finally the tail log is not cleaned but the log file is deleted

Fix suggestion

let upResult;
let logResult;
try {
    [upResult, logResult] = yield Promise.all([upPromise, logPromise]);
}
catch (e) {
    didError = true;
    if(!logResult) logResult = yield logPromise
    throw e;
}
finally {
    onExit(didError);
    yield cleanUp(logFile, logResult);
}
