Dynamic rewrite rules with glob patterns in Firebase - firebase

Question

I have a URL structure to a "project detail" page that looks like this: john/project/eRdKn6 (where "john" is the username and "eRdKn6" is the project id). I want this to be rewritten to the file project.html, where I parse the document.location and load the appropriate data. So the username and the project id should be dynamic.
The rule in firebase.json that I have looks like this:
{
"source": "*/project/*",
"destination": "/project.html"
}
However, Firebase 404's when I try to load http://example.com/john/project/eRdKn6.
I've tried to make only the last part dynamic, as a test (e.g. {"source": "john/project/*", "destination": "/project.html"} but I also get a 404.
The project.html is in the public folder.
Here is my full firebase.json file:
{
"firebase": "example",
"public": "public",
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
],
"rewrites": [
{"source": "*/project/*", "destination": "/project.html"}
]
}

Answer 1

It seems the issue is that source requires a starting slash, e.g. /*/project/*. My full firebase.json now looks like this:
{
"firebase": "example",
"public": "public",
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
],
"rewrites": [
{"source": "/*/project/*", "destination": "/project.html"}
]
}
This seems a documentation issue, since none of the examples cover this use case.
