Summary
The issue arises when using the Power Automate HTTP GET method to retrieve files with specific formats (pdf or jpg) and file names containing special characters (á, é, í). The flow fails after 5 minutes, despite proper encoding.
Root Cause
The root cause of the issue is related to the character encoding and file format. The HTTP GET method in Power Automate has difficulties handling file names with special characters when the file format is pdf or jpg. The causes include:
- Character encoding issues: Special characters in file names are not properly handled.
- File format limitations: pdf and jpg file formats are more prone to issues with special characters in file names.
Why This Happens in Real Systems
This issue occurs in real systems due to:
- Inconsistent character encoding: Different systems may handle character encoding differently, leading to inconsistencies.
- File format specifications: pdf and jpg file formats have specific specifications that may not account for special characters in file names.
Real-World Impact
The impact of this issue includes:
- Failed file retrieval: The flow fails to retrieve the file, resulting in lost data.
- Inefficient troubleshooting: The issue may be difficult to identify, leading to prolonged troubleshooting times.
- Limited file format support: The issue may limit the support for certain file formats, such as pdf and jpg.
Example or Code
# Example of a file name with special characters
$fileName = "nagyméretékezet.pdf"
# Example of a URL with encoded file name
$url = "https://www.jotform.com/uploads/*USERNAME*/*FORMID*/*SUBMISSIONID*/nagym%C3%A9ret%C3%A9kezet.pdf"How Senior Engineers Fix It
Senior engineers can fix this issue by:
- Using URL encoding: Properly encoding the file name in the URL to ensure special characters are handled correctly.
- Implementing error handling: Adding error handling mechanisms to catch and handle exceptions related to file retrieval.
- Using alternative file formats: Considering alternative file formats that are less prone to issues with special characters.
Why Juniors Miss It
Junior engineers may miss this issue due to:
- Lack of experience: Limited experience with character encoding and file format specifications.
- Insufficient testing: Inadequate testing of file retrieval with special characters and different file formats.
- Overlooking error handling: Failing to implement proper error handling mechanisms to catch and handle exceptions.
