rohitgulia opened a new issue, #8784:
URL: https://github.com/apache/incubator-devlake/issues/8784

   ### Search before asking
   
   - [x] I had searched in the 
[issues](https://github.com/apache/incubator-devlake/issues?q=is%3Aissue) and 
found no similar issues.
   
   
   ### What happened
   
   
       bufio.Scanner uses a 64KB default max token size. Python plugins that 
manage
       large numbers of scopes (e.g. 100+ Harness pipelines) return a sync plan 
JSON
       that exceeds this limit, causing silent truncation. This results in only 
a
       subset of scopes appearing in project_mapping and being synced.
      
       Increase the buffer to 5MB in both scanOutputPipe and scanErrorPipe 
   
   eg of what to change: scanner.Buffer(make([]byte, 5*1024*1024), 5*1024*1024)
   
   ### What do you expect to happen
   
   increase scanner buffer from 64KB to 5MB for Python plugin IPC
