Append do not work anymore

[telecomdesign]

Hello

I did a code using append it was working perfectly. I didn't use my code for a week and now it is not working anymore.
Have you ever seen that before ?

my code:
index="my-index"

|append [search (type="repair_event" test_station="test1" )
OR (type="status_event" descriptor_name="test1" )
| stats distinct_count(serial) as r, distinct_count(number) as q by work_order | eval percent_err= round((q/r)*100,100) | eval percent_ok1=(100.00-percent_err)
]

|append [search (type="repair_event" test_station="test2" ) OR (type="status_event" descriptor_name="test2" )
| stats distinct_count(serial) as r, distinct_count(number) as q by work_order | eval percent_err= round((q/r)*100,100) | eval percent_ok4=(100.00-percent_err)
]

| stats first(percent_ok1),first(percent_ok4) by work_order

Thanks for your help

Are you in the same app as you were previously when it worked?

What do you mean by "not working"? What results are you getting now compared to what you were getting a week ago?
