"Manifest parsing has failed" while running teams message extension locally.
Hello paraglombar03
1)Update Manifest Schema and Version:
Ensure that you have updated the $schema and manifestVersion fields in your manifest JSON file to version 1.17.
2)Remove "packageName" Property:
Since version 1.17 does not support the "packageName" property, make sure that you have removed this property from your manifest JSON file.
3)Validate Manifest File:
You can use the Teams Toolkit to validate your manifest file for any errors. Open the command palette (Ctrl+Shift+P) and run the command Teams: Validate manifest file to identify any issues in your manifest.
4) Could you please Clear the cache and try with different tenants.
5)Could you please verify the manifest path and manifest you are uploading is the correct one.
Could you please refer this sample:

Hi vikram-MFST,
First two points have been already implemented. For the third point, please see below screenshot.
Also clear the browser cache. I've just updated existing manifest file not uploaded any external manifest file. Still I am getting the same error.
