Error: Your request is invalid or could not be processed by the service content is not valid Base64

This workflow worked perfectly until a few days ago, I don’t know if it was a version update but I tested two versions and the error persists. I generated a new API key on Github but that didn’t help either.

Hey @leomangueira,

What do you currently have N8N_DEFAULT_BINARY_DATA_MODE set to?

[leomangueira]

Environment=“N8N_DEFAULT_BINARY_DATA_MODE=filesystem”

[leomangueira]

I removed this variable and restarted n8n, updated some files on github but others still give the same error

[leomangueira]

After removing the variable N8N_DEFAULT_BINARY_DATA_MODE the flow works until the second commit, but in the third it gives an error

[Jon]

Hey @leomangueira,

That is interesting, I wonder if there are some characters in the name of the workflow it doesn’t like.

Does that file already exist in the Git repo?

[leomangueira]

The interesting thing is that this file already exists on github and before it was saved normally, the names of the other files contain the same characters. only has - and but no other special characters

[Jon]

Is the - actually a - and are the spaces actually spaces and not another similar character? I have been caught out by sneaky - characters before.

Can you share the workflow name exactly as it is from n8n so I can test if it is the name?

[leomangueira]

got an error on this one: 5-Gerar Livro Fiscal - [PROD].json

These 2 here didn’t give an error:
3-Gravar Notas - Entradas [PROD].json
4-Gravar Impostos e Estoque - NF Outras Saidas [PROD].json

[leomangueira]

I believe it is a failure in the github node, as I committed via vscode and saved normally, I tested several versions of n8n too

[leomangueira]

I discovered the root of the problem. The problem was the file names, it was necessary to add the ID to the name of each file so that it was a unique name.
