This is an awesome tutorial, faced an issue at 32:25, where it says e is of type unknown, To resolve this
update your tsconfig.json file,
{
"compilerOptions": {
"strict": true,
"useUnknownInCatchVariables": false
}
}

Hi Tomas, I really enjoyed this video and your other video where you used DynamoDB instead. I had a problem with this where anytime I try to write to the database, I get an 500 error with Permission Denied for S3 access. How could I fix this?

Hi Aghilan,
Please make sure you have given the correct permissions to the tables, I have explained it here on the video:
for S3 -ruclips.net/video/Bbq3WRtmH0k/видео.html
for DynamoDB - ruclips.net/video/yEJW4V7ddEQ/видео.html
alternatively you can respond with the exact error message you're getting and and I'll send you the correct role statements to paste in your serverless.yml
