How to use the @gatsbyjs/relay-compiler/lib/RelayParser.transform function in @gatsbyjs/relay-compiler

documents.push(doc)
      doc.definitions.forEach((def: any) => {
        const name: string = def.name.value
        namePathMap.set(name, filePath)
        nameDefMap.set(name, def)
      })
    }

    let compilerContext = new GraphQLCompilerContext(this.schema)
    try {
      compilerContext = compilerContext.addAll(
        ASTConvert.convertASTDocuments(
          this.schema,
          documents,
          validationRules,
          RelayParser.transform.bind(RelayParser)
        )
      )
    } catch (error) {
      const { formattedMessage, docName, message, codeBlock } = graphqlError(
        namePathMap,
        nameDefMap,
        error
      )
      nameErrorMap.set(docName, { formattedMessage, message, codeBlock })
      boundActionCreators.queryExtractionGraphQLError({
        componentPath: namePathMap.get(docName),
        error: formattedMessage,
      })
      this.reportError(formattedMessage)
      return false
    }
