cannot get property correctly
I075818 opened this issue · comments
Use VIGA edit tool,run the below json, it will get error message "Cannot read properties of undefined (reading ‘attributes’)" .
If the ‘metric.attributes.pod_id’ is replaced with ‘pod_id’, it works.

Thanks for the report. Can you provide a minimal reproducible example that demonstrates the issue?
Hi domoritz,
Please use this json to debug.

There are no marks in your sample spec. Regardless, I think you just need to escape any property names containing . with \\.
e.g. "_source\\.metric\\.attributes\\.pod_id"
Thank you very much!
