LDF error on 4.2.1

The project that I used to compile fine now comes up with an error, I can’t figure out why.
Can you help me.
I suppose it has something to do with the LDF
Should I put something in the platformio.ini to help find the libs.
before 4.2 was compiling fine…

thank you

What platformio.ini do you have?

[env:nucleo_f303re]
platform = ststm32@~5.3.0
board = nucleo_f303re
framework = mbed
debug_tool = stlink

It seems related to what has been reported also by others:

There are no libraries declared in the platformio.ini. Can you give a list of used libraries and their library.json for reproduction?

I am using mbed project with ble libaries and IDBXA1 st libs:

the file module.json in the lib dir:

{
  "name": "ble",
  "version": "2.7.0",
  "description": "The BLE module offers a high level abstraction for using Bluetooth Low Energy on multiple platforms.",

    },
    "mbed-os": {
      "mbed-drivers": "*",
      "compiler-polyfill": "^1.2.1"
    }
  }
}

Any idea why it does not work? a new bug?

I’d wait for @ivankravets or @valeros to take a look this (and equivalent https://github.com/platformio/platform-nordicnrf51/issues/32) at why

Throws TypeError: string indices must be integers when using these specific libraries.

Hope they fix it quickly. Do you know if it is easy to roll back to previous version of PIO on Visualcode?

You might be able to use a PIO terminal and use the uninstall command together with a pip install platformio==<some version> command, with a version from https://pypi.org/project/platformio/#history and a restart of VSCode. I have not tested this though. Different extension version can be installed easily though (Stop platformio core from updating), but that’s probably not what you want, since the core stays the same.

Could you provide a demo project to reproduce this issue? This works for me

[env:nucleo_f303re]
platform = ststm32@~5.3.0
board = nucleo_f303re
framework = mbed
debug_tool = stlink

Fixed in

Did not get any template youmention in your post. I would gladly attach the project directory if you wish.
Below some configs files in my. project.
Asstated earlier, problems arose only after upgrading to 4.2.1

Any news? Have you had time to investigate.
Thank you for your great support.
Keep up with the excellent work

Hi @franzle! I couldn’t reproduce the issue with that latest platformio-core, so it’d great if you could just run pio upgrade --dev in the VSCode terminal window and try to compile your project again?

Great! Now problem solved with 4.2.2b1!

TypeError: means that you are trying to perform an operation on a value whose type is not compatible with that operation. If you are accessing items from a dictionary , make sure that you are accessing the dictionary itself and not a key in the dictionary. TypeError: string indices must be integers has been caused because you are trying to access values from dictionary using string indices instead of integer.
