Error Description

Token expired. In Frontend SDK integration mode, the token is a one-time credential for a single request, using the JWT format with an expiration time (exp). Filez Document Platform returns this error when token verification finds that the token has exceeded its validity period. Set the validity period to 10 minutes and pass the token to JSSDK for use as soon as it is generated.

Solution

Check token validity period

The token is a one-time credential and its validity period should not be too long. Refer to the example in Signature; 10 minutes is recommended.

Verify server time synchronization

The business system server and Filez Document Platform server must be time-synchronized (NTP). If the clocks on both sides differ significantly, a token may appear valid when generated but be expired by the time it reaches Filez Document Platform.

Avoid caching tokens

The token should be generated in real time by the business system server each time a document is opened. Do not cache it on the frontend or client for reuse. After obtaining the initialization config, call JSSDK to load the document immediately—do not hold the token for an extended period before use.

Check elapsed time from token generation to use

If the business flow is long (e.g., passing through multiple proxies or asynchronous processing), confirm that the total time from token generation to the JSSDK request does not exceed the token's validity period.
