‘falsy value: a.ok(to)’

This is the same question as the now stale

The 'falsy value: a.ok(to)'. error is back

Two months ago, this was a reasonably warm topic: And after a recent upgrade to 1.91.3 (cloud), it’s back. In spades. In brief: All stored workflows work perfectly. However, in-dev workflows (in the active dev UI) throw constant errors, the second time we run any chain (including the simplest debug-style stuff). So, first run is fine, then second run: “Problem Running Workflow: The expression evaluated to a falsy value: a.ok(to)” … and the error repeats on every run after that. This is ha…

TL;DR: doesn’t let me run anything with this strange error, regardless of anything. must do hard browser refresh each time.

the workflow doesn’t matter, it happens on every single node, regardless of configuration.

I can run once, and then the error prevents a consequent run.

After ctrl+shift+R, can run once more, and then again.

It’s impossible to work like this.

The only solution I know is to downgrade to 1.80.5 (now 1.92 but also happens with latest 1.95], but that’s no solution, it doesn’t have basic important features like the ai agent.

Is there ANY workaround? not even hoping for a solution

hello @Noam_Salomonski

Please, share the workflow.

You can select all nodes with ctrl+a, copy it with ctrl+c. Then past the content here after pressing button </> with ctrl+v.
