🛠️ Refactor suggestion

Use JSON-array COPY and quote the pip path; normalize for Windows backslashes

Prevents failures when the requirements path contains spaces or backslashes and makes COPY unambiguous.

-            COPY ${this.options.requirementsFile} ${this.options.requirementsFile}
+            COPY ["${this.options.requirementsFile.replace(/\\\\/g, "/")}", "${this.options.requirementsFile.replace(/\\\\/g, "/")}"]
             # Install dependencies
-            RUN pip install --no-cache-dir -r ${this.options.requirementsFile}
+            RUN pip install --no-cache-dir -r "${this.options.requirementsFile.replace(/\\\\/g, "/")}"

If you prefer readability, precompute the normalized path once and reuse it:

// above, before context.addLayer(...)
const reqFile = this.options.requirementsFile!.replace(/\\/g, "/");

and then:

-            COPY ["${this.options.requirementsFile.replace(/\\\\/g, "/")}", "${this.options.requirementsFile.replace(/\\\\/g, "/")}"]
+            COPY ["${reqFile}", "${reqFile}"]
-            RUN pip install --no-cache-dir -r "${this.options.requirementsFile.replace(/\\\\/g, "/")}"
+            RUN pip install --no-cache-dir -r "${reqFile}"

In packages/python/src/extension.ts around lines 124 to 126, the Dockerfile COPY
and RUN lines can break when requirementsFile contains spaces or Windows
backslashes; normalize the path (replace backslashes with "/") once into a
variable (e.g. reqFile) and then use the JSON-array form for COPY and quote the
pip path in RUN so the COPY is unambiguous and pip receives a quoted, normalized
path (i.e., use COPY ["<reqFile>","<reqFile>"] and RUN pip install
--no-cache-dir -r "<reqFile>").
