@princemaple Does the error point to a file & line number, or is this the full error message? Also, do you have an idea of which file triggered this error? If so, would you mind sharing it's contents so we can see where the parsing failed?

That's all I got. I know which project, that's all. I don't know which file, which module. And no line number was reported. Unless there is a verbose mode that I haven't tried, I think that's all I got.

I have a repo that has several projects in it. I think only one of them is having this issue but don't know which file. I've been migrating the other projects one by one, by limiting the migration path to projects/X.

FYI it's not ng update. Ng update worked fine. It's the separate migration schematic.

Hmm, I have a few guesses on what the root cause could be, but without good error logs I'll have to settle for improving the logging as an intermediary step. I'll try and land something before this Wednesday so it's included in the next patch release 👍🏽

[princemaple]

Thanks a lot 😊 I'll report back when there are more error messages shown.

I'm seeing the same error.

I've narrowed it down to the card component by just selecting and deselecting the options in the CLI, but I cannot find the exact source file it has problems with because it seems to apply all the migrations just fine even if I do not select "card" to be migrated. I am definitely using cards in my project though.

Looking at git, the only thing it adds is some comments in style files where I override some styles and renames mat-chip-list to mat-chip-grid and mat-chip to mat-chip-row.
