TypeError: undefined (reading 'split') queryStr

[Laatem]

When I try to export my panel with InfluxDB datasource, I got this error from the grafana-data-exporter

C:\Users\user\Downloads\Nouveau dossier\grafana-data-exporter-0.5.1\dist\server.js:58892
this._queryParts = queryStr.split(INFLUX_QUERY_TIME_REGEX);
^

But no error with the panel

So I checked the server.js file and did a little debug, I found out that this :

js var queryStr = datasource.params.q;

So basicly here, this script try to get the param "q" from the datasource.params, but my datasource look like this
params: { db: 'dataclient', epoch: 'ms' }, type: 'influxdb', datasourceId: 3
The param "q" is missing, I didn't look further, if anyone has a solution to this problem I would appreciate !
