Lambda function as SQS Event handler doesn’t run a part of code and finishing successfully

I’m using SQS and NodeJS lambda (as SQS Event handler) for creating/updating events in Google Calendar.
The code is similar to this

...
export const handler = async (event) => {
const schemaEvent = getDataFromEvent(event)
console.log('schemaEvent', schemaEvent)
const { data } = await calendar.events.insert({
      calendarId: CALENDAR_ID,
      requestBody: schemaEvent,
      sendUpdates: 'all',
    })
console.log('data', data)

}
...

When SQS receives many events (for ex.: 30), for some of events i can’t see last console.log('Data', data) and code after that doesn’t execute. But, if concurrency is set to 1 it works as expected.
What a reason of the problem can be?

Note:

• BatchSize = 1 for handler
• SQS type is FIFO
• Dedupe is disabled
