[Marukome0743]

TL;DR
SQLITE_READONLY error occurred in InfluxDB 3 Explorer when insert session data.

Steps to reproduce:

1. Run the InfluxDB 3 Explorer following this guide.
2. Go to InfluxDB 3 Explorer webpage.
3. I could see the InfluxDB 3 Explorer dashboard at that time.
4. Around a week later, I couldn't see the dashboard page and homepage shows Error while getting session data.

Expected behaviour:
I can see the InfluxDB 3 Explorer dashboard every time.

Actual behaviour:
InfluxDB 3 Explorer webpage shows Error while getting session data in a week.
