Use ARN authentication may meet ExpiredTokenException occasionally

[lcgogo]

After I add ARN to the datasource and get the databases, tables correctly.

I switch to Explore try to write some query,
some times, I met followed error but it may resume later

ExpiredTokenException: The security token included in the request is expired status code: 403, request id: 5U4D7KK6ZSNY4I3I3DTFUIVMEU

I followed the guide to check
https://aws.amazon.com/premiumsupport/knowledge-center/security-token-expired/?nc1=h_ls
The server metadata shows the token has enough time range

You probably want to remove the tokens and access key since it contains a sensitive information.

hi @lcgogo, that seems like a temporary issue. The timestream data source will continuously pull data for some time. If the token expires while retrieving data, you may see this issue. Refreshing the page should force the token to be refreshed. Are you still able to reproduce this issue?
