Config file not applied

[LesserBabka]

CodeChecker config file does not seem to be applied. I have created a json file according to documentation and help text, to configure my call to CodeChecker. However, regardless of what I put in there it does not seem to be applied.

CodeChecker analyzer version:

---------------------------------------------------------------
Kind                 | Version                                 
---------------------------------------------------------------
Base package version | 6.16.0                                  
Package build date   | 2021-06-10T12:34                        
Git commit ID (hash) | 8880695af939838b2e1e16b018c51ed66c6a5366
Git tag information  | 6.16                                    
---------------------------------------------------------------

Minimal config file (Note: I have also tried replacing "analyzer" with "analyze" as it says in the example config file in the documentation)

$ cat ccc.json 
{
  "analyzer": [
    "--disable=valist"
  ]
}

Invoke check
$ CodeChecker check -b "ninja" -o ./reports --config ccc.json

Info printout includes the disabled check (Full debug output, codechecker_config_file_debug_output.txt)

[INFO 2021-07-21 09:57] - Enabled checkers:
clangsa: ..., valist.CopyToSelf, valist.Uninitialized, valist.Unterminated, valist.ValistBase
...

Disabling the same checker group using the disable parameter works fine
CodeChecker check -b "ninja" -o ./reports -d=valist

This is just an example, I cannot see that any configuration from file seem to be applied.
