Error message when saving product changes

[filipefurtad0]

Description

As reported here - When editing products on the /products page users are getting the message:
Saving failed. Save failed due to invalid data:undefined

Changes seem to be saved anyway, so this is confusing.

Expected Behavior

No error message should be seen.

Actual Behaviour

Saving failed. Save failed due to invalid data:undefined is displayed when saving a product (/products)

Steps to Reproduce

Not sure, it's reproducible but seems a bit erratic. Subsequent changes on the same product: sometimes the error is triggered, some times it is not...

1. Go to the /products page
2. Filter products by enterprise (not sure this is decisive for this bug)
3. Change the name of a product. Click Save Changes
4. Repeat till you see the error... -> obviously some detail is missing here. Not sure what could that be....

This one would deserve the wtf label:

Workaround

The user should ignore the error message.

Severity

bug-s4: it's annoying, but you can use it

Confusing to the users, and seems to have generated reports to support teams. Worth upgrading to s3?

Hi Filipe, thanks for logging this bug. Confirming that I've also replicated the bug in Chrome (MacOS Sierra 10.12.6):

Hi @filipefurtad0

I will try to do a deep dive for this issue

[filipefurtad0]

Hey @sinansonmez 👋
Please feel free to do so.
It does seem tricky find the root cause, as it does not always happen. So, in case you get stuck, please to drop a line and move to another one 👍

[sinansonmez]

Yeah @filipefurtad0 you are right it is kinda hard to reproduce it. I tried many times in my local, but no luck :( . I see that you reproduced this issue in staging environment. I will try couple more time tomorrow in my local to reproduce

[sinansonmez]

Update from my side. Unfortunately, I couldn't reproduce the issue. I will look for sth else to work on it

@filipefurtad0 I tried this a couple of times as well and I cannot reproduce. Can you see if you are able to achieve this now?

[filipefurtad0]

Hey @georgethoppil ,
This was appearing in very unspecific circumstances... Indeed I can't reproduce it in my test setups.

@adele-ofn: can you still verify this bug in production?

[RachL]

As we cannot reproduce it for now. I'm closing this one :)

I think I can reproduce this one (I've been editing thousands of products today to change some tax cagegories, and I think I see a pattern). I am finding that this error reliably presents when 2 conditions are met: (1) a product is deleted from the list and (2) a product is changed after that deletion. At least I think so... Just deleting a product does not give the error. Just changing a product doesn't seem to give the error.
