Kedro-viz crashes randomly with JavaScript type error after adding changes to pipeline registry

AArtur Dobrogowski

Hi, I have a weird bug to report, but I'm not sure how to investigate it/debug. After adding some benign changes to pipeline registry, kedro-viz (9.2.0) started to randomly crash with javascript type error at some pipelines (resulting in whole screen going white-blank and needs to refresh). Those are the changes between commits (before commit all works fine, after commit it consistently crashes on some (seemingly somewhat random - the lower the pipe in the list the higher chance to crash) subset of pipelines with uncaught exception). That's the whole diff of the commit:

@@ -79,7 +79,16 @@ def register_pipelines() -> dict[str, Pipeline]:
             group_class, input_schema, pipelines[f"training_{group_class}"], pipelines[f"inference_{group_class}"]
         )
 
-    pipelines = {k: pipelines[k] for k in sorted(pipelines.keys())}  # sorting for kedro-viz selection box
-    pipelines["__default__"] = sum(pipelines[f"training_and_inference_{gc}"] for gc in GROUP_CLASSES)  # type: ignore

+    # pipelines = {k: pipelines[k] for k in sorted(pipelines.keys())}  # sorting for kedro-viz selection box
+    order = ["input", "data", "feature", "fgu", "layer", "pricing", "inference", "training"]
+    pipelines = {
+        k: pipelines[k]
+        for k in sorted(
+            pipelines.keys(),
+            key=lambda x: str(order.index(x.split("_")[0]) if x.split("_")[0] in order else len(order)) + x,
+        )
+    } # reordering pipelines in kedro-viz based on order list
+    pipelines["__default__"] = pipelines["input_na"]

Hi Artur, Have you tried to check how your pipelines list looks before and after reordering? In other words, does it contain what you expect?

EElena Khaustova

, any ideas on what can cause such a behaviour?

AArtur Dobrogowski

Yes it's what I expect

AArtur Dobrogowski

Before it was lexical order and now it's order as in the list order, and everything else is at the end

AArtur Dobrogowski

I was also confused about ordering dict, as afaik it does not guarantee keeping order

EElena Khaustova

I see, I’m curious whether issue remains if you remove your changes but randomly shuffle the pipelines dict after creation.

EElena Khaustova

This can narrow down the error

RRashida Kanchwala

Can you share traceback of the javascript error ? Thanks

AArtur Dobrogowski

I was looking at it but it is minified and not really useful, but I can do that

RRashida Kanchwala

no worries, if u can share what u have on the github bug report. we will try to replicate the error at our end. and reach out if more help is needed. thanks

AArtur Dobrogowski

is this what you asked for?

RRashida Kanchwala

u r right, this is not helpful. we will have to replicate this error at our end to understand better -- let me know once u have opened the bug report on github and we can start to investigate

AArtur Dobrogowski

do u have idea how I can provide you a more useful error log?

AArtur Dobrogowski

I'll try to DL kedro viz react from npm maybe its not minified

RRashida Kanchwala

i think we have an idea , it might be related to a bug related to hard coding the '<i>default</i>' pipeline so for now, just the above should be fine. and u don't face this issue in kedro-viz 9.1 right ?

AArtur Dobrogowski

didn't test it on 9.1

RRashida Kanchwala

also cc -

AArtur Dobrogowski

can test on 9.1

AArtur Dobrogowski

yup it works on 9.1.0

AArtur Dobrogowski

so I'm not going to report a bug then, since you know better what's wrong

RRashida Kanchwala

it will still require some investigation. if u could we can triage it better. thanks 🙂

KKacper Leśniara

Hey hey! Coming back to this issue, which is really hard to debug -> Kedro-viz just stops working randomly on some pipelines and just renders a white screen. Doesn't happen at all on 9.1.0 but breaks on 9.2.0 and 10.0.0 unfortunately. Nothing is happening in the terminal, the web console spits out.

We commented out pipeline sorting and __default__ pipeline overwriting to pinpoint the problem. Any ideas?

JJuan Luis Cano Rodríguez

thanks and sorry you're having a bumpy ride. it's clear that the traceback isn't useful and also that this is a regression from 9.1.0 we should investigate.

can you please open an issue in https://github.com/kedro-org/kedro-viz/issues with the behavior in 9.1.0 vs 9.2.0 ? as well as the output of kedro registry list before and after your registry change

We think that 10.0 introduced a different error than the previous one

KKacper Leśniara

Is there a way to provide you with a more descriptive error message? Cloned the kedro-viz repo hoping that I can run it in some kind of a dev mode

AArtur Dobrogowski

and the crashing behavior is inconsistent

Hey Kacper, We can quickly jump to call to debug this ?

SSajid Alam

We replaced toposort with graphlib between 9.1.0 and 9.2.0 perhaps that might be causing the issue.

Consider adding an error boundary to your tree to customize error handling behavior.

Somehow a tag has no name which results in node.text becoming undefined and breaking in match function

JJitendra Gundaniya

Hey ,
Are you still facing same error after running kedro run on the problematic pipelines?
if no, Is it the same case for both 9.2.0 and 10.0.0 Kedro-Viz version ?
Let me know if you are still facing the issue, we can connect tomorrow.

KKacper Leśniara

I believe it was the same error in 9.2.0 and 10.0.0. As a workaround we just got rid of the tag and it seems to be working, but no idea what's causing it to become undefined
