Here's a simplified view of my situation:

I have two lambda functions (A and B). Function A invokes Function B for some of its processing.

I'm looking for some way to have Function B be capable of understanding that it is Function A making the call, in a secure and "most simple" way. In other words; Function B is exposed to the internet via an API Gateway, but how can I ensure that invocations are made by a trusted party?

My key-word here is "Simple"; of course, I could generate API keys and store those in Dynamo or whatever, but that feels needlessly complex when I'd be perfectly happy just knowing "Hey, this request was made by LambdaRole123". where LambdaRole123 is the role that Func

Question here that I feel should be obvious, but I can't seem to figure out.

I'm trying to create a CodePipeline which begins with a Source step (as they do), connecting to a private, organization-owned Github repository. I am also trying to do this with a customer-managed OAuth token (aka Personal Access Token), because I want to "templatize" this CodePipeline and dynamically create them with a lambda function in response to PR events (basically this architecture here).

I am creating a Pipeline using the CDK, which maps to CloudFormation templates. The relevant CDK lines are (in TypeScript):

// We'll move this token to secrets m

I'm running into a very strange issue with my PC that I could use some help diagnosing. Full spec list:

• Asus Strix x470I Motherboard
• Ryzen 5 2600x
• Corsair DDR4-3000 1x16gb
• Samsung 970 Evo
• Zotac GTX 1070 (Mini)

Full story: When I first built the PC a few weeks ago, I was getting errors left and right that resembled this:

OneDrive.exe - Application Error The instruction at 0x00000077ADCC5B referenced memory at 0x000000000014. The memory could not be read. Click on OK to terminate the program.

The name of the program could be anything, oftentimes the program I have running, like BlizzardLauncher.exe or something like that. The memory addresses were always random. The program

I've recently built a new computer, with a brand new install of Windows 10 Pro. If it is relevant, the specs are listed below:

• Asus Strix x470I Motherboard
• Ryzen 5 2600x
• Corsair DDR4-3000 2x16gb
• Samsung 970 Evo
• Zotac GTX 1070

Immediately after installing, after using the OS for a bit, an error will pop up that says something like:

OneDrive.exe - Application Error The instruction at 0x00000077ADCC5B referenced memory at 0x000000000014. The memory could not be read. Click on OK to terminate the program.

Depending on what I'm doing, the application might change; for example, after installing graphics card drivers, sometimes the application will be "NVLink.exe", or if I

What is your parts list?

• Asus ROG Strix x470i
• Ryzen 5 2600x
• Zotac GTX 1070 (Mini)
• 2x16gb Corsair DDR4-3200
• Samsung 970 Evo 1TB SSD
• Windows 10 Pro

Describe your problem. List any error messages and symptoms. Be descriptive.

Installed Windows 10 Pro, and began the process of driver updates. Using Asus ezUpdate I started with the BIOS. Installed them and restarted. The computer restarted, followed by a new pre-boot screen which had a progress bar, which completed, followed by another restart, and then nothing.

On the motherboard there is a status LED light. On boot it goes Orange (checking RAM) followed by Red (checking CPU). It'll stay on Red for about 60 seconds befor
