Problems deploying (brandingset) via VS Code

Question

I have this package.xml:

    <types>
        <members>LEXTHEMINGTR2C2</members>
        <name>BrandingSet</name>
    </types>
    ...
    <types>
        <members>R2C2</members>
        <name>LightningExperienceTheme</name>
    </types>

In the file structure I do have the files

LEXTHEMINGR2C2.brandingSet-meta.xml

R2C2.lightningExperienceTheme-meta.xml

Also, in the LightningExperience.settings-meta.xml file I have this:

<activeThemeName>R2C2</activeThemeName>

So I guess I'm doing alright with the sources.

But, when deploying (deploy source in manifest to org) to a destination org, I get these two errors:

API: In field: defaultBrandingSet - no BrandingSet named LEXTHEMINGR2C2 found

Lightning Experience (Settings) In field: developerName - no LightningExperienceTheme named R2C2 found

Is there anything I'm missing here?

Answer 1

I made it!

As it turns out (in a trial-and-error exercise), the prefix "LEXTHEMING" is useless. I removed any reference to the prefix.

In the package.xml I just let the branding set name as it was:

<types>
    <members>R2C2</members>
    <name>BrandingSet</name>
</types>

The file name is R2C2.brandingSet-meta.xml (as it should be).

And it worked.
