ReferenceError: require is not defined

[pensono]

I often get an error message like this one.
ReferenceError: require is not defined

Why does it happen? What should I do to work around it?

[Workflow] Error while running workflow {
  workflowRunId: 'wrun_01KJ34497C1A7Z97YD8KS2T8VY',
  errorName: 'ReferenceError',
  errorStack: './workflows/backfill:22445\n' +
    'var import_os = __toESM(require("os"), 1);\n' +
    '                ^\n' +
    '\n' +
    'ReferenceError: require is not defined\n' +

workflow: 4.1.0-beta.57,
turbo: 2.5.8,
next: 16.1.1,

I traced the issue down to an import from the posgres package.

I was able to fix the issue by reorganizing my steps so that the function I imported from this package was only used in a step and not in a workflow.

The error message is quite confusing though, there's no context as to why this happened. For example, it would have been useful to see somewhere that this error occurred when evaluating in the workflow's context.

same issues. I don't even know which step or which library caused the problem.

Noting that this can happen if there's a bad import in any of the files any workflows, not just the one which you are trying to start.
