AWS Bedrock Error: 'ReadTimeoutError' When Calling AWS Bedrock # aws # bedrock # devops # cloud A diagnostic guide to resolving AWS Bedrock inference failures caused by client-side read timeouts. Problem An AWS Bedrock invocation fails with a read timeout error. Typical symptoms: Python (Boto3 / Botocore):   ReadTimeoutError Node.js:  Request hangs, then fails with a timeout General:  Connection succeeds, but no response is returned before the timeout expires Inference may have started, but the caller aborts the request. Clarifying the Issue This is  not  an IAM issue. This is  not  a client mismatch issue. 📌 This error occurs when  Bedrock takes longer to return a response than the client’s read timeout allows . 📌 A read timeout happens  after  the connection is established, while waiting for inference output. Why It Matters ReadTimeoutError  is common when: Prompts or outputs are large High-latency models are used Streaming is d...

  The Secret Life of AWS: The Vault (AWS Secrets Manager) # aws # security # devops # cloud Stop hiding keys under the doormat. How to manage passwords with AWS Secrets Manager. Part 25 of The Secret Life of AWS Timothy was finishing up his security review from  Episode 24 . He turned to Margaret with a look of accomplishment. "I have secured the perimeter with WAF," he said. "And I also cleaned up my code. Look." He pointed to his Python script. # Before # db_password = "SuperSecretPassword123!" # After db_password = os . environ [ ' DB_PASSWORD ' ] "I removed the hardcoded database password," Timothy explained proudly. "Now it is stored as an Environment Variable in the Lambda configuration. It’s much safer." Margaret smiled gently. "That is a great first step, Timothy. Hardcoding secrets is like leaving your house key right in the door lock." "But," she paused, leaning in closer to the screen. "U...

The Secret Life of JavaScript: The Promise (Microtasks) # javascript # coding # programming # softwaredevelopment Understanding the VIP Line: Microtasks vs. Macrotasks. Timothy sat at the small library table, shuffling two pieces of paper. He looked up as Margaret approached, a frown creasing his forehead. "I don't get it," he said quietly. "I told the code to wait zero milliseconds. Zero. That should be instant, right?" He slid a code snippet across the table. console . log ( " 1. Start " ); setTimeout (() => { console . log ( " 2. Timeout " ); }, 0 ); Promise . resolve (). then (() => { console . log ( " 3. Promise " ); }); console . log ( " 4. End " ); "I expected it to go 1, 2, 3, 4," Timothy explained. "Or maybe 1, 4, 2, 3. But look what actually happened." 1. Start 4. End 3. Promise 2. Timeout <-- Why is this last? "The Timeout was set to zero," Timoth...

  The Secret Life of AWS: The Bodyguard (AWS WAF & Shield) # aws # cybersecurity # devops # cloud When your API is under attack, AWS WAF & Shield protect your door and your wallet. Part 24 of The Secret Life of AWS Timothy was smiling as he looked at his dashboard. "Look at this, Margaret," he said, pointing to the screen. "My new marketing campaign must be working. I have 10,000 requests per minute hitting the Checkout API." Margaret leaned in, her expression curious but cautious. "That is impressive growth, Timothy. But... look at the error rate." Timothy frowned. He clicked deeper. "That's strange. 90% of them are  400 Bad Request . And they are all coming from the same block of IP addresses." "And look at the payload," Margaret said gently. "They aren't sending order data. They are sending gibberish code, trying to trick your database." Timothy’s face fell. "It's not customers. It's an attack....

  The Secret Life of Python: The Hidden Return # python # coding # programming # softwaredevelopment Why your function result is  None  — and how to fix it. Timothy beamed as he looked at his screen. He had just finished refactoring his pricing script into neat, organized functions, exactly as Margaret had shown him. "It feels so much cleaner now," he said, hitting  Run . "Let's see it working." The screen flashed. Calculating Tax... Tax is: 15.0 Final Price: None Timothy’s smile faded into a look of genuine puzzlement. "That's odd," he said softly. "The final price is  None . But right there on the line before, it printed '15.0'. I wonder where the number went?" Margaret looked up from her desk and smiled. "Do you want a second pair of eyes?" "Please," Timothy said. "I'm not sure what I missed. Inside  calculate_tax , I calculated the  tax  variable. It definitely holds  15.0  because I printed it. B...
