When I was importing a brand new development un-managed solution into QA environment, I faced this weird error. The import file is too large to upload.


Attempt 1:
The link added  Help me resolve this issue. was not useful in my case as it says chances of Duplicate column names which is not true in my solution. I have downloaded the log file to dig more.


When I scrolled all the way down to see the unprocessed rows. Gotcha! There was a Business rule which caused lot of trouble in Unit testing itself like not triggering at all in Quick create. So I get rid of it.

Attempt 2:
Again when I tried to import the latest solution in QA, failed this time with the same error message. Again download log & dig.... This time a new culprit!

CanvasApp import: FAILURE: One or more errors occurred.


Canvas App import failure. voila! I was trying some cool Canvas Power App into my Model driven Power App (our same CRM UCI app :)) but not so fruitful. So some messy left overs bothering me now.

1. Delete the CanvasApps folder
2. Remove this line in solution.xml

     

3. Clean up/Delete the below entry in [Content_Types].xml

 PartName="/CanvasApps/xxx_xxx_e4543_BackgroundImageUri" ContentType="application/octet-stream"/>

4. Remove this below portion from customizations.xml
