TypeError: Cannot read properties of undefined (reading 'sha')

[tconroy]

Hello! Thank you for your work on this stack, it's really great!

I'm running into a strange issue. I've published some posts, but I can't seem to update them. If I commit and deploy a changes to the markdown file associated with a post, I am still seeing the initial version of that post when deployed to production.

I'm not sure entirely what is causing this issue, but I did notice this error during the Determine Changes step on CI:

Run echo ::set-output name=DEPLOYABLE::$(node ./others/is-deployable.js)
TypeError: Cannot read properties of undefined (reading 'sha')
    at go (/home/runner/work/***/***/others/is-deployable.js:7:30)
    at processTicksAndRejections (node:internal/process/task_queues:9[6](https://github.com/tconroy/my-repo/runs/7243487957?check_suite_focus=true#step:5:7):5)

Wonder if that could be related? I've seen this undefined error relating to sha crop up a few times in my CLI with this stack.

Hey!
The script cannot fetch the build sha from the deployed Fly app. The fetch operation happens here.

Can you check if you have configured FLY_APP_NAME as part of the actions secret?

If that is configured correctly, can you visit https://<FLY_APP_NAME>.fly.dev/build/info.json and check if info.json is present and has the sha value. (Sample info.json)

If it's not there, can you check the build logs in GitHub action? (A successful build should look like this).

[tconroy]

Thank you for the help!

✅ I just double-checked that I have the FLY_APP_NAME in my GitHub actions secret.

My info.json only contains timestamp:

{
"timestamp": 1657252585158
}

In the build logs, nothing super crazy jumps out to me, other than this line:

#19 4.530 💣 fetch failed with Cannot read properties of undefined (reading 'author')

I also tried to manually trigger a POST call to the https://<MY_FLY_APP>.fly.dev/_content/refresh-content endpoint with the REFRESH_TOKEN and the payload { "refreshAll" true }.

This returns a 500 response from fly.io.

I looked at the logs and saw this (note: i've truncated out my ipv6 address):

This is odd. I'm not sure why the request would fail. I confirmed the IP address is correct (by comparing it with the output of flyctl ips private). any idea why that request would return ENOTFOUND?

Interestingly, I am now seeing the sha info in my info.json. So that's good!

However, I am still not seeing my content refresh.

I think the error above (500 response on the update-content fetch) is the root cause here, but not sure why it's working OK for you but not for me 🤔

I'm facing the same issue. Let me open an issue at Fly. I'm not sure why the fetch call to the IP is failing 😕. Thanks for the report!

[tconroy]

Thanks! Please share what you find. I tried starting a thread over in the fly.io community but have not yet gotten an answer.

[tconroy]

Just following up on this. I did not get a satisfactory answer from Fly or elsewhere. I ended up hard-coding the address (ie instead of using the ipv6 values, I just did http://<my-domain>.fly.dev. That works, but I worry it wont scale to multiple instances.
