Sudden increase in Gmail API 500 errors when sending emails

Hey everyone, I’m having trouble with our app’s email sending feature. We let users connect their Gmail accounts to send emails through our system. It’s been working fine for years, but now we’re getting a bunch of complaints.

Here’s a snippet of how we’re sending emails:

def send_email(message):
    api_endpoint = 'https://gmail-api.example.com/v1/users/me/messages/send'
    headers = {'Content-Type': 'message/rfc822'}
    
    response = requests.post(api_endpoint, data=message, headers=headers)
    
    if response.status_code != 200:
        raise Exception(f'Gmail API error: {response.text}')
    
    return response.json()

The weird thing is, many users are getting 500 errors now. The error message just says ‘Internal error encountered’ with a ‘backendError’ reason.

We’ve tried to figure out what’s causing it. Is it affecting certain types of accounts? Specific email content? We even tried to recreate the issue using our test accounts.

Has anyone else run into this lately? Did Gmail change something on their end? Any ideas on how to fix this or what might be causing it? Thanks for any help!

hey there, ive been seein similar issues lately. might be worth checkin if youre hittin any rate limits or if theres been any changes to gmail’s api recently. have u tried implementing exponential backoff for retries? that could help with temporary hiccups. also, make sure ur error handling is robust to catch n log these 500s for better debugging.

I’ve encountered similar issues recently. It’s possible Google has made changes to their API without clear documentation. Have you verified your OAuth credentials are still valid and up-to-date? Sometimes these can expire unexpectedly. Another potential cause could be changes in Gmail’s spam detection algorithms, flagging certain emails as suspicious. It might be worth implementing more detailed logging to capture the full request and response data for these 500 errors. This could provide valuable insights into any patterns or specific triggers. Additionally, consider reaching out to Google’s support channels directly, as they might have more information on any recent backend changes affecting API stability.

I’ve been grappling with this exact issue for the past couple weeks. It’s frustrating, to say the least. From what I’ve gathered, Google’s been rolling out some backend changes that are causing these 500 errors. What’s worked for me is implementing a more robust error handling system. I’ve set up automatic retries with exponential backoff, and it’s helped smooth things out considerably. Also, I’ve found that breaking down larger batches of emails into smaller chunks has reduced the frequency of these errors. It’s not a perfect solution, but it’s kept our system running without major disruptions. Might be worth giving that a shot while we wait for Google to sort out whatever’s going on on their end.
