Minimal length for User Id

[ZoharBergman]

We are using Amplitude Node SDK for events reporting.
While implementing, we've noticed that when trying to log an event and attach it a user id that its length is lower than 5 chars, we get an error:
Status code: 400, Status: invalid, Response body: {"error":"Invalid id length for user_id or device_id", ...}.
To overcome this error, we concatenated 5 leading spaces, after that, the error has gone and the logEvent function succeeded (we also validated that the leading spaces are trimmed in the Amplitude analytics site).

Could you please fix this issue, to avoid the 5 leading spaces trick?

• SDK Version: 1.5.3
• Node version: 15.6.0

Hi @ZoharBergman. We suggest users stick to the minimum ID length (see here), but it can be overridden. The Node Client accepts an optional parameter minIdLength that will override the default minimum id length when set.
