Array buffer allocation failed


Could you tell me something about that deployment error?

Serverless: Invoke aws:common:validate
Serverless: Invoke aws:deploy:deploy

Range Error --------------------------------------------

Array buffer allocation failed

 For debugging logs, run again after setting the "SLS_DEBUG=*" environment variable.

Stack Trace --------------------------------------------

I tried to resize de memorySize at serverless.yml but didn´t work, I think maybe is caused by the zip file that is trying to upload to aws (130M).


Did you every find anything about this issue? I am just running into this issue now and can’t find any documentation online about it.


Hey, I also got that error. It was solved by re-install “nvm” and “npm”.
After install both of them, I have these versions:

[root@ip-xxx-xx-xx-xxx build-scripts]# npm --version
–> 5.7.1

[root@ip-xxx-xx-xx-xxx build-scripts]# nvm --version
–> 0.33.8

I hope this workaround also works in your site,

For your info,
After pass the first error “Array buffer allocation failed”, now I am getting this one:

Serverless Error ---------------------------------------
An error occurred: TagComplianceSubscribeLambdaFunction - Unzipped size must be smaller than 262144000 bytes.
Stack Trace --------------------------------------------

And the root cause is because of Unzipped size (> 250 Mb).

We can confirm it, by checking the AWS lambda limits:

Indeed, it looks like the “Array buffer allocation failed” is related to the Unzipped files size.
