issue calling wikidata-cli from php on webserver

[HakanIST]

Hello, I'm using wikidata-cli inside a php bot. When I execute the php script from shell it works fine, but when I run in on webserver I get the following error. Any suggestions what may be the problem?

function is

shell_exec('wd sparql ./team.rq -j');

path.js:39
    throw new ERR_INVALID_ARG_TYPE('path', 'string', path);
    ^

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type undefined

it looks like it can't find a $HOME directory where it could initialize config files; is the $HOME variable set in this environment? If not, a workaround could be to define one before the command: shell_exec('export HOME=/tmp; wd sparql ./team.rq -j');.

You can also now update to v7.0.2 where it tries to recover from this missing environment variable by running without persisting the config
