regex issues after recheck / output gone

[th12289]

Describe the bug

regex issues after recheck / output gone

Version
v0.45.24

To Reproduce

Steps to reproduce the behavior:

I am tracking for example the follwing url:
https://www.otto.de/mode/sportmode/sportschuhe/laufschuhe/stabilitaetsschuhe/?marke=asics,asics-sportstyle&schuhgroesse-eu=46&zielgruppe=herren&sortiertnach=preis-aufsteigend

Filters and triggers
CSS/JSONPath/JQ/XPath Filters

//*[@id="reptile-tilelist"]

and nothing anything else. just the following regex:

/.*laufschuh.*|.*€.*|.*extra.*/

thats my output if i clear history and this is the correct one:

    Asics GT-1000 13 Laufschuh für mehr Stabilität
      129,99 € 11,87 € mtl. in 12 Raten
          -20% Extra
      129,99 € 11,87 € mtl. in 12 Raten
          -20% Extra
    Asics GT-2000 12 Laufschuh für mehr Stabilität
      159,99 € 14,61 € mtl. in 12 Raten
          -20% Extra
      159,99 € 14,61 € mtl. in 12 Raten
          -20% Extra
    Asics GEL-KAYANO 31 Laufschuh für mehr Stabilität
      199,99 € 18,27 € mtl. in 12 Raten
      199,99 € 18,27 € mtl. in 12 Raten

after i push "recheck" without changing anything my output is nothing.
This happens on many of my configured sites.

Expected behavior
Same output as before (or changes if website had changes)

Screenshots

output after clearing history

output after recheck is nothing

Desktop (please complete the following information):

• All OS with a browser
• Browser Edge, Safari
• Version newest updated

Additional context
If there are more as one regex entrys, there are sometimes no issues with line 2,3,4.... its just with the first one.

example:

        /.*laufschuh.*|.*€.*|.*extra.*/
        /.*€.*/

Also if i use the first regex and duplicate it, that there are 2 times the same entrys, it works sometimes but with a doubled output.

output after duplicated entry

Hello @dgtlmoon

first thank you for answering. I have collected some more information to clarify.

i use Extract text and i have changed "laufschuh" to "gel"

Before i was going into my bed, all rules were resetted with "clear/reset history"
and it was correct first.

These were the changes over night: (theres a last row with sidenotes)

URL	CSS/JSONPath/JQ/XPath Filters	PDF Print of Edit	Changes over night with first correct output	sidenote
OWL Dampfer	//*[@id="product-list"]	owldampfer.pdf	owldampfer_changes.pdf	Just 4 lines left
Asics Outlet Neutral	/html/body/div[2]/div[4]/div[4]/div[2]/div[5]/ul/li[*]/a	asicsoutletneutral.pdf	asicsoutletneutral_changes.pdf	removed everything
Otto	//*[@id="reptile-tilelist"]	otto.pdf	otto_changes.pdf	removed everything
Zalando	none	zalando.pdf	zalando_changes.pdf	collects 1 of 3, but after reset history it is/was correct
Size Official	none	sizeofficial.pdf	sizeofficial_changes.pdf	removed everything
Asics Outlet Stable	/html/body/div[2]/div[4]/div[4]/div[2]/div[5]/ul/li[*]/a	asicsoutletstable.pdf	asicsoutletstable_changes.pdf	removed everything

Example images of URL 1-3

Example Configurations without changes over night and right output

I don't know if this helps, but it seems like it reduces after time.
I have changed nothing.
Just my hourly checks worked.

Example:
https://www.owl-dampfer.de/OWL-SALT?af=100

---

First output

Output 2 hours later

Output 8 hours later

some more information:

• the output changes unregularly - it adds and removes. it does not only removes.
• my notifications are triggered even if there are no changes
• if i delete my regex and work without - there are no issues

i hope this helps a bit :)

thank you so much for your work

[dgtlmoon]

if you change from xpath to css, does it still happen?

so from //*[@id="reptile-tilelist"] to #reptile-tilelist

Hello @dgtlmoon

Short answer: yes, it still happen

i changed to

Can you click the 'share' link and paste that link here?, it will be easier than trying to copy/paste/understand your settings exactly from what you wrote

[th12289]

Yes, i've opened my instance public to share.
Sorry and thank you again.

Hello,

ive made a complete new docker instance and copied all checks to the new.
my issue is now solved. this is maybe related to old corrupt volume files.

thank you for all
