Error during deployment regarding concurrency

[mvanaltvorst]

Thank you for this project, it is precisely what I was looking for. However, I encounter an error when I try to deploy a basic configuration:

╷
389
│ Error: error setting Lambda Function (tf-next_tfn-deploy) concurrency: InvalidParameterValueException: Specified ReservedConcurrentExecutions for function decreases account's UnreservedConcurrentExecution below its minimum value of [50].

Have you encountered this error before, or do you know where I might be able to learn more about what might be causing this? Thank you.

Hey, sorry for the late answer.

Looks like this has something to do with other Lambda functions deployed to your AWS account.
Another issue from the Serverless framework provides some explanations why this error message might occur: https://forum.serverless.com/t/unreservedconcurrentexecution-below-its-minimum-value-of-100/10323/4

I'm also getting this error playing w/ the free-tier. My account has Full account concurrency of 50, and the proxy lambda consumes 1, which brings it under the minimum value 50.

How does one reduce the minimum value?

@mvanaltvorst Did you get this resolved? If not, you can request a quota increase on your main region:
https://us-west-2.console.aws.amazon.com/servicequotas/home/services/lambda/quotas/L-B99A9384

I think anything above 50 would work, but I requested 200 just to be sure. It takes 2-3 days for AWS to confirm the request.

Saw this today in a newly created AWS account too.

Looks like AWS drastically decreased the quota value here:

Requesting an increase should work, will add this as a doc entry to the repo.

Added a support document for this issue here: Function decreases account's UnreservedConcurrentExecution below its minimum value

Also pinged the AWS support about the issue here: https://twitter.com/milliHQ/status/1488592847825780743
