Why am I getting this error when deploying (running remote build): Expecting value: line 1 column 1 (char 0)

I am trying to deploy a Python script that requires external libraries from a windows machine. I have tried using a .sh build script like in all of the digital ocean sample repos. But that gives me an error that won’t run on this platform, and no build.cmd is provided. So I try to replace it with a build.cmd but it gives me json decoding error in my logs.

This is the final output it gives me Error: While deploying action ‘test-slack-2/test’ (running remote build): Expecting value: line 1 column 1 (char 0)

Hi thank you for the help and quick response. But that didn’t work my VS code environment already uses LF and when I ran the through dos2unix it still gave me the error below.’ won’t run on this platform and no ‘build.cmd’ is provided

And trying to run dos2unix on build.cmd gives the same error as well.

Hi there,

It sounds the issue might be related to newline characters in your script files. Windows and Linux use different newline characters: Windows uses \r\n (carriage return and line feed), while Linux uses \n (line feed).

To resolve this issue, you can try converting your build script and other relevant files to use the appropriate newline characters for your target platform (Linux in your case).

Here are a couple of ways to convert newline characters:

  1. Using a text editor: Many text editors, such as Notepad++, Visual Studio Code, or Sublime Text, allow you to change the newline characters’ format. You can usually find this option in the editor’s settings, preferences, or status bar. Look for “Line Endings” or “EOL Conversion” and change it to “Unix (LF)”.

  2. Using dos2unix tool: If you have access to a Unix-based system or WSL (Windows Subsystem for Linux) on your Windows machine, you can use the dos2unix tool to convert the newline characters. To use dos2unix, install it first, and then run the following command:


Replace with the name of your script file. This command will convert the newline characters in the file to Unix-style line endings.

After converting the newline characters, try deploying your Python script again.

Let me know how it goes!
