Lambda function package not found error

Question

I have added package through layer but getting error like this 
I followed this post to Manually create a Lambda layer that uses the latest Boto3 version

Error : Layers consume more than the available size of 262144000 bytes

Answer

Hello.

The error is caused by Lambda's package size limit.  
Does it include any other large packages besides Boto3?  
If it only contains Boto3, I don't think it will be that size, so the layer creation method may be incorrect.

You can also get around size limits by using container images with Lambda.

Answer

Lambda has a maximum size of 250mb of all layers when extracted.

How big are your layers when extracted?
