CostCo - browserless:server Error with inbound socket Error: read ECONNRESET (Costco.com)

[OffalGood]

Using ChangeDetection 0.40.1.1 with playwright running in docker stack.

I have an watch alert for item in costco.com. I setup playwright browser steps to a) Wait 10 sec, b) enter zipcode, c) click element, so Costco will show inventory availability. It works when I manually run thru the steps, but it will fail when ChangeDetection runs it on schedule, or force a check now.

Playwright says "consecutive_filter_failures", and then err out with ECONNRESET.

Browser Steps:

1. Wait for Seconds: 10
2. Enter text in field: //*[@id="eddZipCodeField"], "Your zipcode"
3. Check element: #edd-check-button Click Enter

Any suggestions on how to fix or how to troubleshot?

Thanks!

Could you share the watch link?

@b4bbuilder Here you go.

Thx for looking.

@OffalGood there's two big problems with your watch

• The element you click after filling in the text (#edd-check-button) is just a div, not a button so just change it to press enter
• I think you misunderstand the 'visual selector', you have told it to follow the 'buy now' button but this is just a button and doesnt have any html with text, so the system doesnt know it changed, remove this from your filters

second thing, what is the goal of this watch, what is it that you want to achieve? your watch seems like a mix of ideas

[dgtlmoon]

I tried this on our paid hosting environment and it works perfectly https://changedetection.io/share/K8gstF9MXQ4a

the goal of this shared watch is to keep an eye on the estimated delivery date

hope it helps!

What exactly do you mean by " so Costco can check availability. " ? what is expected?

@dgtlmoon
Yeah, this is quite new to me, so I am fudging my way thru and hopefully learning along the way. Thanks for your pointers! 😁

1. My use case is to check when item come back in stock on Costco.com. I gave the wrong example above, so I've updated the URL.

2. Thanks for highlighting the 2 issues around "Click element" and visual indicator.

3. I used your shared example, and got the following error below.

When I connected to browserless docker session, I noticed that the webpage does not have input field to enter the zipcode. Could that be causing the error below?

Any more pointers and help would be very much appreciated. Thanks!
