Python debugging broken with new containers #289

Closed cnelsonvelo closed 4 years ago

cnelsonvelo commented 4 years ago

When attempting to debug using Pycharm today new containers were downloaded automatically and the debugging fails with this error:

Connected to pydev debugger (build 201.6668.115) Traceback (most recent call last): File "/tmp/lambci_debug_files/pydevd.py", line 1438, in _exec pydev_imports.execfile(file, globals, locals) # execute the script File "/tmp/lambci_debug_files/_pydev_imps/_pydev_execfile.py", line 18, in execfile exec(compile(contents+"\n", file, 'exec'), glob, loc) File "/var/runtime/bootstrap", line 4 if [ -z "$AWS_LAMBDA_EXEC_WRAPPER" ]; then ^ SyntaxError: invalid syntax

Reverting to an earlier version of the python3.8 containers, and preventing Pycharm from automatically updating them resolves the issue temporarily.

This seems to have broken AWS SAM cli as well.

Same here File "/var/runtime/bootstrap", line 4 if [ -z "$AWS_LAMBDA_EXEC_WRAPPER" ]; then ^ SyntaxError: invalid syntax

I moved to python3.7 for now and it is working.

@mhart could you help us with that?

mhart commented 4 years ago

Well AWS Lambda did update a bunch of runtimes today – and the bootstrap files changed on them.

Unfortunately I'm not familiar with how Pycharm integrates these containers – is it expecting something in particular?

The python3.8 image seems to execute fine for me – without doing any complicated debugging or anything.

@therealjeffg can you be more specific about what broke with SAM CLI?

mhart commented 4 years ago

Yeah, this is an issue with aws-sam-cli – it's assuming that /var/runtime/bootstrap is a python file – but Lambda has changed it to be a bash file (hence the syntax error).

I'll file an issue over at the sam repo

The Lambda runtimes have been rolled back – hopefully this won't raise its head again!
