Hey, great video.
I needed some assistance.
How do I save the output in a S3 bucket?

[@lovetocode4486]

Hi Sushil,
You can easily use boto3 client to save the content to S3. The code is something similar to this.
import boto3
S3_RESOURCE = boto3.resource('s3')
MY_BUCKET = S3_RESOURCE.Bucket('your bucket name')
req = 'this is your content'
MY_BUCKET.put_object(Key=''your_s3_object_key', Body= req)
Let me know how it goes

Do you get any error in the cloudwatch log?
Try adding 'S3FullPermission' to the role which attached to the lambda. Hope this is a permission issue

hello what event did you used?

[@lovetocode4486]

do you mean how does the lambda trigger? if so, you can add a Event notifications for the S3 bucket which can trigger the lambda. please check this for more info docs.aws.amazon.com/AmazonS3/latest/userguide/EventNotifications.html
Hope this helps you. :)

[@SamuelGrabois]

@@lovetocode4486 i did the part when we use the bucket as the trigger but my code giveme an error that says that it doesnt recognices this line " file_obj = event["Records"][0]" and i was thinking it has something to be with the event of the file

while using console and tryinig to detect text for sample image i am facing this error "Textract encountered an error while processing this document." Any idea about it. Thankyou!!

[@lovetocode4486]

Hi Yash,
It is hard to say why you are getting the error without more info. Do you get any error if you use the Python code I mentioned above for the same image?

[@betallyoungattractive644]

I did not get any output. I also checked the logs and there are no errors. Did we need to substitute some values in the lambda function code before triggering the process? Thanks for your help.

[@lovetocode4486]

Hi Mate,
As per below code piece, the lambda is triggered by S3 event.
github.com/CodeSam621/Demo/blob/e5b5f538d41411478981008e8d9956d83d9da5e1/AWSTextract/lambda_function.py#L63
If you are triggering the lambda using the testing utility of lambda, then you need to send the event object which has " event["Records"][0]" data

[@betallyoungattractive644]

@@lovetocode4486 Yeah, I triggered the lambda by placing the file in the S3 bucket but it produced no output and there were no errors in the logs. I was just curious if you have seen this issue before and if you had any suggestions what the issue might be?

[@lovetocode4486]

​@@betallyoungattractive644 ,
What I recommend to do are:
- Add log (very beginning of the lambda function) to make sure that the lambda is trigger. Then upload a file to S3. This add some logs to the cloudWatch logs.
- Once you verified above step, add necessary logs to see where it broke.

Hi, great video. I need your assistance. How to store the Output in S3?

[@lovetocode4486]

HI
Saving to the S3 is easy. Just pass the bucket name, file_Id and the content(json) to below method.
```
import os
import json
from boto3 import resource
import uuid
import logging
logger = logging.getLogger()
logging.basicConfig()
logger.setLevel(logging.INFO)
S3_RESOURCE = resource('s3')
def save_payload(bucket, key, content):
COI_BUCKET = S3_RESOURCE.Bucket(bucket)
response = COI_BUCKET.put_object(Key=key, Body=json.dumps(content))
logger.info(f'save_payload to s3. Response: {response}')
return response
```

[@lovetocode4486]

Hey mate,
Do you mean that lambda logs in cloudWatch? If that is the case, seems the lambda is not triggered. How did you trigger the API Gateway? Do you get any error when trigger API Gateway?

[@Imphanda]

Can you try doing it with rekognition?

[@lovetocode4486]

Hi @Nancy,
The Textract is more suitable and advance for this kind of work. eg: extract content from forms etc.
This comes with more advance things like "QUERY" which can used to extract element.
On the other hand, the Rekognition good more identify context from the image. eg: give an image and see what sort of image it is.
