Type Error

[j3nsykes]

I'm getting a TypeError: Cannot read properties of undefined (reading 'replace')
with a simple Q and A chain from a text file. This is following the video tutorials provided so not sure what the issue is. I see in other discussions people deleted nodes and started again but this does not resolve the issue in this instance.

resolved by starting a new chatflow from scratch. Would like to know a more efficient way to resolve this error though

I have the same ERROR and no other ideal than starting again from scratch...

I deployed 1.6.3 on a Railway server and have a similar error with my flow.
Sometimes it works the first query after redeploying. But then I get:

TypeError: (intermediate value) is not iterable (cannot read property undefined)

always.

On my local Flowise installation on a Windows Server and the excact flow, I never saw this problem.
