CloudWatchLog is showing KeyError, as follows:

[ERROR] KeyError: 'Content-Type'Traceback (most recent call last):  File "/var/task/lambda_function.py", line 13, in lambda_handler    content_type = event["headers"]['Content-Type']

After print(event) , I noticed that it should be 'content-type' not 'Content-Type'.

Great tutorial on API Gateway on Youtube. Love it.

This file has the below code which attempts to put the text into a .txt file and sends to the same bucketName which will cause another object to be placed into the same bucket which in turn invokes Lambda again.
This bucket name should be changed to a separate bucket to avoid recursion if you want to view the text in .txt file in S3.

           s3.put_object(
                Bucket=bucketname,
                Key=f"output/{filename.split('/')[-1]}_{uuid.uuid4().hex}.txt",
                Body=str("\n".join(raw_text)),
            )

Hi,
please let me know how to resolve this issue.I followed your youtube tutorial "How to upload file with metadata - Amazon API Gateway p13" but while running API through postman it is getting error --->{
"message": "Could not parse request body into json: Could not parse payload into json: Unrecognized token 'LS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLTg5NTE2NzMyNDY5NzM4ODUwNDgxNzA1NA0KQ29udGVudC1EaXNwb3NpdGlvbjogZm9ybS1kYXRhOyBuYW1lPSJmaWxlIjsgZmlsZW5hbWU9IldvcmtzcGFjZSAtIEF6dXJlIE1GQSBTZXR1cC5wZGYiDQpDb250ZW50LVR5cGU6IGFwcGxpY2F0aW9uL3BkZg0KDQolUERGLTEuNAol4uPP0woz...': was expecting (JSON String, Number, Array, Object or token 'null', 'true' or 'false')\n at [Source: (byte[])"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"[truncated 475584 bytes]; line: 1, column: 257]"
}

The pdf that is uploaded to the S3 bucket is blank i.e. the pdf is formed of the same name as given in metadata and also the no of pages is also preserved but every page is blank without any content.
