Issue when modifying dashboard including text tile

[sampitcher]

Gazer version = v0.2.14
Looker version = 6.16.10

We have a customer set up on 2 instances, dev and prod. We are modifying content in dev instance, then promoting content to prod when changes have been made using gzr. We need to keep the dashboard slugs from dev to prod the same so links do not break..
The majority of dashboards move over fine, however if a dashboard contains a text tile we get this error message:

Modifying existing dashboard 2 E-commerce | Direct control tower in space 9

  "type": "text"
})

So far I have to remove the text tile in dev content and then add it in manually in prod.

Thank you!

Same here, on version 6.14
@sampitcher I noticed this doesn't occur on text tiles with body, so my workaround was to add an empty html body e.g <center></center>

Also seeing this on 6.20.15.
We see this on text tiles with body, but no title or subtitle. Adding an empty title would make the tile too large for the dashboard.

Although it only fails when it is attempting to overwrite an existing dashboard (using --force). If I move the existing dashboard to trash and delete from trash, the import works without error.

I just pushed gazer version 0.2.19. I believe that will fix this issue. If it does not fix we can reopen.
