query.exclude() gives error but no additional logs.

Hi. When I use exclude method in my cloud code, I get this error with no additional logs:

{"code":141,"level":"error","stack":"Error\n    at error (/root/parse/node_modules/parse-server/lib/Routers/FunctionsRouter.js:121:16)\n    at runMicrotasks (<anon$
{"functionName":"getHomeObjects","error":{"code":141},"params":{},"user":"Tw8o5jj3DJ","level":"error","message":"Failed running cloud function getHomeObjects for u$

This is console log:

Input: {}
  Error: {"code":141} {"functionName":"getHomeObjects","error":{"code":141},"params":{},"user":"Tw8o5jj3DJ"}
error: Parse error:  {"code":141,"stack":"Error\n    at error (/root/parse/node_modules/parse-server/lib/Routers/FunctionsRouter.js:121:16)\n    at processTicksAndRejections (internal/process/task_queues.js:97:5)"}
error: Failed running cloud function getHomeObjects for user Tw8o5jj3DJ with:

This error happens only when I use exclude method on queries. I use exclude method to exclude some array list from obbject

For example:
query.exclude("words");

The thing is this happens random. I have other cloud codes which uses same query but on different Class. It works but some other class it doesn't work.

I formatted my server and did a clean install but I still got the error.

But if I remove exclude, cloud code works fine

My parse server version is 4.2.0
My MongoDB version is also 4.2.0
Database is in localhost.

Start by reproducing the getHomeObjects cloud function with and without query.exclude("words"), then inspect the failure path mentioned in lib/Routers/FunctionsRouter.js at line 121. Compare the affected class and query with the working case; done means the exclude failure is reproducible and produces useful diagnostic output or is fixed.
