It sounds like there might be an invalid character in your file names. Can you post a full stack trace from the logs?

@brianjhanson Please see stack trace below:

Hm, not much useful in there. Is this happening to every image? Or specific images? If it's happening on specific images, is there anything different about them (same filetype, special characters in the filename, etc.)?

When you say "after moving site", did you move the site to a new server (keeping the asset storage the same between servers)? Or recently move the assets over to Google Cloud from another service?

[seanjessen]

Yes this is happening to every image where transform parameters are passed into getUrl() on the frontend and also thumbnail transforms in the backend. If no parameters are passed into getUrl() on the frontend the images do get returned.

It was after creating a local development copy using valet that this occurs but it also occurs on a separate staging environment as well. Just the live site functions as it's supposed too. As far as I'm aware the assets have always been hosted on Google Cloud.

[brianjhanson]

Very odd. If the live site is working it sounds like an environmental issue vs. one directly with Craft. Did you double check that your credentials file is correct and that the plugin is pointed to the correct path?

[seanjessen]

Yes I checked both of those and the error still persists. It also occurs on image upload through the admin panel specifically with this error returned: Control character error, possibly incorrectly encoded

[brianjhanson]

Any chance there's a \n in your credentials somewhere? If so, can you make sure those are properly escaped?

[seanjessen]

@brandonkelly there was indeed an unescaped character in one of the environment variables. Thanks for your help!

[brandonkelly]

Good guess @brianjhanson!
