Logic App fails to get file content from GitHub

Lakshana 20

Hi, I'm trying to work on an automatic KB update.. where when a file gets created or modified in GitHub, the logic app should be triggered, get the file content and save the data in azure AI Seacrh. But I've been facing with an issue which I'm not sure how to resolve.

I am using GitHub webhook to trigger the logic app, that works fine but when logic app tries to retrieve the file content using the GET request, it throws an Internal Server Error.

Hi Lakshana,

Based on the information shared, I understand that you created a GitHub webhook to monitor changes to a specific file. If any changes occur, it should trigger the logic app to update the file in Azure AI Search.

If my understanding is correct, Github webhooks are used to subscribe to specific events on GitHub that occur in a repository.
From the existing Github documentation, there is no specific webhook that can help to pull the specific files from repository

Could you please share more details to understand the issue better

Have you created that webhook trigger by following this documentation steps (Use a webhook as a trigger for Azure Logic Apps and Power Automate by creating a custom connector

Which specific trigger you are using in logic and which action you are using to get the file from GitHub?

Are you following any documentation if yes please do share it?

If you are using built-in connector what actions & triggers you are using in your workflow.

Hi @Lakshana,

Firstly, created a custom Connector with webhook:

enter image description here

Later, to get the file content, I have used Parse Json action to parse the trigger body.

Then, used Compose to get modified file name. In my example, I have done it for modified files, you can also do for new files which are created by adding a parallel action.

enter image description here

I am getting the output as ["filename"] in Parse Json action , so modified it to filename using below function in Compose Action:

for modified:

replace(replace(replace(string(items('For_each')?['modified']), '[', ''), ']', ''), '"', '')

for created :

replace(replace(replace(string(items('For_each')?['created']), '[', ''), ']', ''), '"', '')

Then, used the http action:

enter image description here

GET https://api.github.com/repos/{owner}/{repositoryname}/contents/{path/filenname.ext}

You can also get Owner name, Repository Name and all from Parse JSON action only, but I have given it manually.

My repository is public, so did not gave any authorization, if yours is private then need to give PAT token in authorization header while calling the file content.

Output:

enter image description here

This is how I get the content of GITHUB files using Logic apps.

Hope this helps.
