I have build my own osquery with new table, when I run she shell it works well also the new table. but when I run the service and I run query on him the service getting stopped and but gets the result from that query, and this problem happening from any query. when see at the logs I get the next error message: osquery extention "{my path of extention}" (-1) stopping Cannot find process. when I delete him from flag file it works well. but the thing that is strange that the extension did not make any errors to my old osquery version (4.8). @Kathy Satterlee

I think your best bet is to post more details about exactly what you tried and what error(s) you encountered. That would make it easier for people to help you.
