Corresponding front-end error net:: err_INCOMPLETE_CHUNKED_ENCODING 200

How to Solve:

After ES re extracts the data, the data of one field becomes particularly large, resulting in a particularly large package when returning to the front end, resulting in too large response data of nginx. Temporary files will be used for processing, but the user does not have the permission to operate this directory, so the service is stopped directly. Finally throw the above error.

Solution:

1. Check the error log of nginx (/data/000x/nginx/logs/error.Log)

2021/12/01 12:05:40 [crit] 66289#0: *680 open() "/data/000x/nginx/proxy_temp/2/02/0000000022" failed (13: Permission denied) while reading upstream, client: 192.16.199.1, server: localhost, request: "POST /api/search/result HTTP/1.1", upstream: "http://127.0.0.1:17803/search/result", host: "192.16.199.20:17002", referrer: "http://192.16.199.20:17002/pc/"

2. To/data/000x/nginx/proxy_Temp grant permission

Done!!!
