InvalidParameterValueException: Invalid dead letter ARN: ARNs must start with 'arn:'

[seoker]

As I know, the latest release supports the config of Dead Letter Queue, but it seems not compatible with previous settings.
If don't specify the dead letter config explicitly, the config will be DeadLetterConfig: { TargetArn: '' } by default, and then it turns into the following error:

InvalidParameterValueException: Invalid dead letter ARN: ARNs must start with 'arn:':

Also, I don't know what event source mapping files are and don't want to use it, is there any way to bypass the file exist checking or not setting event_sources.json by default?

[abetomo]

@seoker I'm sorry. InvalidParameterValueException has been reproduced. to correct.

[abetomo]

@seoker seoker I'm sorry. I opened the PR #209 of bugfix.

[seoker]

@abetomo Thanks, what a quick resolve! Any thoughts related to event_sources.json which I comment in #208 (comment)?

[abetomo]

@seoker

event_sources.json is created in node-lambda setup, but if you are using 0.8.15, it will not load that file by default.
It must be explicitly specified with EVENT_SOURCE_FILE of .env or -S option and it will not be loaded.

Is it likely to solve with the above contents?

[seoker]

@abetomo
Thanks, I think I was encountering this issue by 0.8.14 when I was falling back version to test the dead letter config issue. Anyways, waiting for the new version to be released, thanks a lot!

[abetomo]

@seoker I think that the modified version has been released, but how about after that?

[seoker]

Oh sorry, it's solved by f3ff683.

[abetomo]

Thank you for confirmation!

[turjachaudhuri]

I am still getting this issue as of 13.03.2018 . Any ideas on what to do?

[abetomo]

@turjachaudhuri What kind of error message is displayed?

[eberkund]

I am getting the following with v0.12

I notice the config it prints out has

DeadLetterConfig: { TargetArn: '' } }

[abetomo]

@eberkund It seems that the role specification is not good.
What kind of values are you setting?
